Abstract
Purpose
This study aims to examine the effects of coworker incivility on employees' behaviors using a moderated mediation model that conceptualizes coworker exchange (CWX) as a mediator and servant leadership as a moderator.
Design/methodology/approach
The data were collected using a multi-temporal research design. The hypotheses were tested on a sample of 1,272 participants using confirmatory factor analysis (CFA), hierarchical regression analysis and moderated path analysis. In addition, supervisor incivility was added as a control variable to partial out the potential influence on employees' behaviors.
Findings
The results of CFA ensured that all measures had discriminant and convergent validity. In addition, the results of hierarchical regression analysis and moderated path analysis indicated that CWX mediates the relationship between coworker incivility and employees' behaviors. Furthermore, servant leadership exacerbates the negative relationship between coworker incivility and CWX.
Practical implications
Leaders and practitioners should invest in communication training programs for developing employees' communication skills to avoid incivility. In addition to viewing incivility as inappropriate behavior, leaders and practitioners should understand the meaning beyond those incivilities.
Originality/value
This study utilized incivility spiral theory to examine how coworker incivility affects employees' behaviors. The mediated path analysis found that CWX mediates the relationship between these variables, which has been ignored by previous research. Furthermore, this study introduced servant leadership as a moderator to account for the “when” in incivility spiral theory, i.e. what kind of social context facilitates or inhibits the influence of coworker incivility on CWX.

Abstract
Purpose
The purpose of this study is to determine simultaneously the period of preventive maintenance and the sequence of each job for two parallel machines problem so that the makespan is minimized. With proper planning of preventive maintenance, a shop can avoid lack of flexibility between maintenance planning and production scheduling, and thus concentrate on production efficiency.
Design/methodology/approach
This study addresses a scheduling problem, wherein each machine has to be shut down for maintenance during a maintenance interval [C, T] arranged in advance. The start time and end time of the preventive maintenance are the decision variables. A maintenance action is attended by a server who managers only one machine at a time. Three cases are studied in this paper: the unequal lengths of unavailable periods on both machines, the equal lengths of unavailable periods on both machines, and no waiting time is allowed between the two unavailable periods. Each case is solved optimally by an analytical algorithm developed in the study.
Findings
Although having exponential time complexities, all the proposed algorithms are quite efficient in solving large‐sized problems. Computational results show that it is able to generate the optimal solution for large sizes (up to 10,000 jobs) in a few minutes of computation time.
Practical implications
Most of the papers that dealt with preventive maintenance assumed that the maintenance period is known and specified. However, the flexible preventive maintenance problem, in which the start time and end time of the preventive maintenance are the decision variables, often occurs in the computer center, NC‐machine and IC‐testing machine for job scheduling and repairs arrangement.
Originality/value
The paper presents an efficient approach for each of the three cases of flexible preventive maintenance, which is relatively unexplored in the literature.
