This study among 332 police officers examines the effects of performance appraisals from a behavioral ethics perspective. A mediation model relating justice perceptions of police officers' last performance appraisal to their work affect, perceived supervisor and organizational support and, in turn, their ethical (pro-organizational proactive) and unethical (counterproductive) work behavior was tested empirically. The relationship between justice perceptions and both, ethical and unethical behavior was mediated by perceived support and work affect. Hence, a singular yearly performance appraisal was linked to both ethical and unethical behaviors at work. The finding that ethical and unethical aspects of employee behavior share several of the same organizational antecedents, namely organizational justice perceptions, has strong practical implications which are discussed as well. http://repub.eur.nl/res/pub/22247/ 2012-03-01T00:00:00Z There is a lack of consistent evidence that downsizing leads to improved financial performance. Lowered commitment after painful downsizing periods is identified as an important reason why downsizing does not show the intended long-term effects. This paper provides a meta-analytical overview of the impact of fairness on organizational commitment for survivors and victims after a downsizing operation. Among 37 samples (11,256 persons), a positive relationship was found between fairness and affective organizational commitment (ρ=0.40) for both survivors and victims. Three moderators of the fairness–commitment relationship were identified: (1) for survivors, procedural justice matters more than distributive justice; (2) the impact of fairness is stronger in countries with an individualistic (versus collectivistic) culture; (3) fairness matters more when mass layoff is initiated for profit maximization (versus economic necessity).
