A theoretical assessment of dismissal rates and unit performance, with empirical evidence.

Unit-level dismissal rates have rarely been studied, but utility analysis suggests that increasing dismissal rates can improve performance by increasing the contribution of a unit's workers. This proposition comports with other theory around dismissals but contradicts substantial empirical evidence. We extend the staffing utility framework, taking a multilevel perspective and attending to both within- and between-unit effects of dismissal rate practices. We test our theory in monthly observations from 1,047 retail locations over almost 3 years. Our results explain how between-unit associations between workforce contribution and unit performance can mask the within-unit benefit of increasing dismissal rates. This insight reconciles theory with prior evidence, although some researchers have interpreted them to be at odds. A better understanding of the complex causes and consequences of dismissal rates has the potential to open new avenues of research and inform practice in ways that promote unit effectiveness.
