Abstract
Purpose
This study developed new measures of the routine and non-routine task contents of managerial, professional, technical, and clerical occupations from a workload perspective. Here, we present a comparative analysis of the workload structures of state and industrial sector employees.
Design/methodology/approach
Our method involves detailed descriptions of work processes and an element-wise time study. We collected and analysed data to obtain a workload structure that falls within three conceptual task categories: (i) non-routine analytic tasks, (ii) non-routine interactive tasks and (iii) routine cognitive tasks. A total of 2,312 state and industrial sector employees in Kazakhstan participated in the study. The data were collected using a proprietary web application that resembles a timesheet.
Findings
The study results are consistent with the general trend reported by previous studies: the higher the job level, the lower the occupation’s routine task content. In addition, the routine cognitive task contents of managerial, professional, technical, and clerical occupations in the industrial sector are higher than those in local governments. The work of women is also more routinary than that of men. Finally, vthe routine cognitive task contents of occupations in administrative units are higher than those of occupations in substantive units.
Originality/value
Our study sought to address the challenges of using the task-based approach associated with measuring tasks by introducing a new measurement framework. The main advantage of our task measures is a direct approach to assessing workloads consisting of routine tasks, which allows for an accurate estimation of potential staff reductions due to the automation of work processes.

Abstract
Purpose
Recently, physical crafting has been found to positively affect emotional exhaustion through workload. However, the role of cognitive crafting in this process remains unexamined. To address this research gap, this study examined the relationship between cognitive crafting and emotional exhaustion, as well as whether cognitive crafting moderates the positive indirect effects of physical crafting on emotional exhaustion through workload.
Design/methodology/approach
The data were collected through an Internet survey conducted with 2,143 Japanese employees, and path regression analysis was conducted to analyze the data.
Findings
The results show that cognitive crafting was negatively correlated with emotional exhaustion, weakened the relationship between workload and emotional exhaustion and weakened the indirect effects of physical crafting on emotional exhaustion.
Practical implications
The practical implications of these findings suggest that practitioners should encourage the improvement of cognitive crafting. Implementation of job crafting interventions and customer participation could be effective in enhancing cognitive crafting.
Originality/value
The study provides a deeper understanding of how cognitive crafting influences emotional exhaustion and how it influences the process through which physical crafting influences emotional exhaustion, aligning with the transactional model. The results reiterate the importance of cognitive crafting, an aspect that has received little attention since the introduction of the job demands-resources (JD-R) model of job crafting.

Abstract
Purpose
As data centres grow in size and complexity, traditional air-cooling methods are becoming less effective and more expensive. Immersion cooling, where servers are submerged in a dielectric fluid, has emerged as a promising alternative. Ensuring reliable operations in data centre applications requires the development of an effective control framework for immersion cooling systems, which necessitates the prediction of server temperature. While deep learning-based temperature prediction models have shown effectiveness, further enhancement is needed to improve their prediction accuracy. This study aims to develop a temperature prediction model using Long Short-Term Memory (LSTM) Networks based on recursive encoder-decoder architecture.
Design/methodology/approach
This paper explores the use of deep learning algorithms to predict the temperature of a heater in a two-phase immersion-cooled system using NOVEC 7100. The performance of recursive-long short-term memory-encoder-decoder (R-LSTM-ED), recursive-convolutional neural network-LSTM (R-CNN-LSTM) and R-LSTM approaches are compared using mean absolute error, root mean square error, mean absolute percentage error and coefficient of determination (R2) as performance metrics. The impact of window size, sampling period and noise within training data on the performance of the model is investigated.
Findings
The R-LSTM-ED consistently outperforms the R-LSTM model by 6%, 15.8% and 12.5%, and R-CNN-LSTM model by 4%, 11% and 12.3% in all forecast ranges of 10, 30 and 60 s, respectively, averaged across all the workloads considered in the study. The optimum sampling period based on the study is found to be 2 s and the window size to be 60 s. The performance of the model deteriorates significantly as the noise level reaches 10%.
Research limitations/implications
The proposed models are currently trained on data collected from an experimental setup simulating data centre loads. Future research should seek to extend the applicability of the models by incorporating time series data from immersion-cooled servers.
Originality/value
The proposed multivariate-recursive-prediction models are trained and tested by using real Data Centre workload traces applied to the immersion-cooled system developed in the laboratory.

Abstract
Purpose
Drawing on conservation of resources theory, this study aims to examine how employees’ experiences of excessive workloads may direct them away from efforts to share knowledge with other organizational members, as well as the circumstances in which this process is more or less likely. To untangle the process, the authors predict a mediating role of job dissatisfaction and moderating roles of two complementary resources that help employees cope with failure: resilience as a personal resource and organizational forgiveness as an organizational resource.
Design/methodology/approach
Survey data were gathered from employees of an organization that operates in the construction retail sector. The Process macro provides an empirical test of the moderated mediation dynamic that underpins the proposed conceptual framework.
Findings
The statistical findings affirm that an important channel through which employees’ perceptions that their work demands are unreasonable escalate into a diminished propensity to share knowledge is their lack of enthusiasm about their jobs. Their ability to recover from challenging work situations and their beliefs that the organization does not hold grudges against people who commit mistakes both mitigate this harmful effect.
Practical implications
For organizational practitioners, this research shows that when employees feel frustrated about extreme work pressures, the resource-draining situation may escalate into diminished knowledge sharing, which might inadvertently undermine their ability to receive valuable feedback for dealing with the challenges. From a positive perspective, individual resilience and organizational forgiveness represent resources that can protect employees against this negative spiral.
Originality/value
This study explicates an unexplored harmful effect of strenuous workloads on knowledge sharing, which is explained by employees’ beliefs that their organization fails to provide satisfactory job experiences. This effect also is mitigated to the extent that employees can draw from valuable personal and organizational resources.

We empirically assessed the antecedents of subjective well-being at work for French permanent employees.
Abstract
Purpose
We empirically assessed the antecedents of subjective well-being at work for French permanent employees.
Design/methodology/approach
The methodology includes qualitative and quantitative data analyses. In the first phase, interviews elicited the antecedents of subjective well-being at work among permanent French employees. In the second phase, a questionnaire survey was used to confirm the relevance of the antecedents uncovered in the first phase.
Findings
We found 14 distinct elements that influence French employees’ subjective well-being at work: corporate culture, job dissonance, relationships with colleagues, achievement, professional development, relationships with superiors, status, workload, perks, feedback, workspace, diversity and pay. Moreover, we identified discrete antecedents for the three components of subjective well-being at work: work achievement and relationships with superiors and colleagues for positive emotions at work, job dissonance and workload for negative emotions at work and organizational culture and professional development for satisfaction with one’s work.
Originality/value
The original contribution of this study is to have unpacked the black box of the antecedents of subjective well-being in the French workplace and to have uncovered discriminant predictors for each of the three components of subjective well-being at work. Furthermore, we specifically linked each of these three components with their most significant antecedents.

Abstract
Purpose
This study aims to propose an efficient dual-robot task collaboration strategy to address the issue of low work efficiency and inability to meet the production needs of a single robot during construction operations.
Design/methodology/approach
A hybrid task allocation method based on integer programming and auction algorithms, with the aim of achieving a balanced workload between two robots has been proposed. In addition, while ensuring reasonable workload allocation between the two robots, an improved dual ant colony algorithm was used to solve the dual traveling salesman problem, and the global path planning of the two robots was determined, resulting in an efficient and collision-free path for the dual robots to operate. Meanwhile, an improved fast Random tree rapidly-exploring random tree algorithm is introduced as a local obstacle avoidance strategy.
Findings
The proposed method combines randomization and iteration techniques to achieve an efficient task allocation strategy for two robots, ensuring the relative optimal global path of the two robots in cooperation and solving complex local obstacle avoidance problems.
Originality/value
This method is applied to the scene of steel bar tying in construction work, with the workload allocation and collaborative work between two robots as evaluation indicators. The experimental results show that this method can efficiently complete the steel bar banding operation, effectively reduce the interference between the two robots and minimize the interference of obstacles in the environment.

Abstract
Purpose
There is currently a shortage of applications for the role of principal. There are a range of factors contributing to this, one of which may be the considerable levels of stress and burnout reported by principals and deputy principals. Distributed leadership may offer some solutions to this challenge. This study aimed to explore the lived experiences of distributed leadership from a role sustainability perspective of school principals and deputy principals.
Design/methodology/approach
This paper follows a qualitative interpretivist approach based upon 15 semi-structured interviews with principals and deputy principals working in Irish post-primary schools. Data were analysed via thematic analysis.
Findings
Results indicate challenges to the sustainability of the role of senior school leaders comprising administrative overload, policy proliferation and challenges due to the complexity and breadth of the role of these school leaders. It was reported that engagement with distributed leadership could aid the sustainability of participants in their roles and the importance of focusing on well-being practices was also highlighted.
Practical implications
Recommendations include the need to reconsider policy proliferation and the need to reconceptualise school leadership. Further consideration regarding how distributed leadership can aid the sustainability of the role of senior school leaders, without adversely contributing to the already busy role of schoolteachers is also recommended.
Originality/value
The findings of this study are valuable as they reflect previous findings relating to the current challenges to sustainable school leadership as well as highlight distributed leadership as a potential aid to mitigate against these challenges.

Abstract
Purpose
This paper aims to present commentary on adult safeguarding designated officers’ (nominated senior staff members in the Health Service Executive and its funded services) in Ireland readiness for online learning and their perception of the blended approach used in their training and considers the implications of this for practice.
Design/methodology/approach
In total, 233 designated officers were surveyed. A self-administered online survey comprising of two instruments was used. The questionnaire combines two previously validated tools measuring readiness for online learning and perceptions of blended learning. Minor modifications were made to account for local circumstance and language. Demographic questions relevant to the survey population were added. The response rate was 49%.
Findings
Designated officers regarded specified competencies for online learning as important to very important with highest importance placed in time management. Designated officers expressed they were confident to very confident in their ability to accomplish all competencies in online learning. The highest confidence was in the technical competencies. Designated officers are demonstrating high readiness for online learning. Designated officers reported positively on online contributions and on blended learning workload. The scores indicate positive perceptions of the blended learning experience. Responses to an open-ended question were largely positive with some suggestions for improvement made.
Practical implications
Findings have helped inform planning and development of the Health Service Executive’s adult safeguarding training for designated officers with changes made since this survey was undertaken.
Originality/value
To the best of the author’s knowledge, this is the first time a survey was undertaken of designated officers in Ireland with a view to improving safeguarding training. Recommendations for adaptions to the blended designated officer programme were proposed and subsequently accepted and implemented.

Abstract
Purpose
Large class sizes are becoming the norm in higher education against concerns of dropping learning qualities. To maintain the standard of learning and add value, one of the common strategies is for the course convenor to proactively monitor student engagement with learning activities against their assessment outcomes and intervene timely. Learning analytics has been increasingly adopted to provide these insights into student engagement and their performance. This case study explores how learning analytics can be used to meet the convenor’s requirements and help reduce administrative workload in a large health science class at the University of New South Wales.
Design/methodology/approach
This case-based study adopts an “action learning research approach” in assessing ways of using learning analytics for reducing workload in the educator’s own context and critically reflecting on experiences for improvements. This approach emphasises reflexive methodology, where the educator constantly assesses the context, implements an intervention and reflects on the process for in-time adjustments, improvements and future development.
Findings
The results highlighted ease for the teacher towards the early “flagging” of students who may not be active within the learning management system or who have performed poorly on assessment tasks. Coupled with the ability to send emails to the “flagged” students, this has led to a more personal approach while reducing the number of steps normally required. An unanticipated outcome was the potential for additional time saving through improving the scaffolding mechanisms if the learning analytics were customisable for individual courses.
Originality/value
The results provide further benefits for learning analytics to assist the educator in a growing blended learning environment. They also reveal the potential for learning analytics to be an effective adjunct towards promoting personal learning design.

Abstract
Purpose
This paper aims to investigate how perceived working conditions affect employee performance, including safety compliance and task performance, through employee well-being (i.e. job satisfaction) in the context of the coal mining sector in China.
Design/methodology/approach
This paper uses the job demands-resources model to test the relationships between working conditions, including job demands (work pressure as a challenge demand and perceived risks and hazards in the workplace and ineffectiveness of the safety system as hindrance demands), job resources (interpersonal harmony), job satisfaction and performance. This study adopts a two-wave design with a three-month lag to reduce possible common method bias.
Findings
Employees who experienced high level of challenge demands, e.g. time pressure workload, reported higher levels of task performance, and this positive relationship seemed to be robust. There is a direct effect of perceived ineffectiveness of the safety system on task performance, while the relationship between perceived risks and hazards and task performance was fully mediated by job satisfaction. Challenge demands, i.e. work pressure, did not impact much on employees’ well-being, and thus job satisfaction did not mediate the relationship between work pressure and performance. Perceived ineffectiveness of the safety system was negatively associated with safety compliance. This result is not surprising since a lack of effective safety system reflects management’s ignorance of workplace safety, which demotivates employees to enact safe behaviors. In contrast, the presence and implementation of an effective safety system would be interpreted by employees as management exhibiting a high level of commitment. Work pressure was positively not negatively related to safety compliance. One possible explanation for this finding is that the effects of work pressure on safety compliance behaviors might be dependent on contextual factors such as safety climate. Interpersonal harmony moderated the relationships between work pressure and employee performance (both safety compliance and task performance) and the relationship between perceived risks and hazards and task performance, but the role of interpersonal harmony appeared more complex. There was no significant correlation between challenging job demands and individual employee performance when there were higher levels of interpersonal harmony. The relationship between perceived risks and hazards, a hindrance job demand and task performance became positive as interpersonal harmony increased but negative as interpersonal harmony decreased.
Originality/value
This paper provides a robust integrative theoretical framework that better explains the various types of job demands and job resources in the working environment of coal mining sector in China and their relationships to employee performance. The findings also offer valuable guidance for managers trying to identify effective ways to enhance employee performance and safety in the workplace.
