“…For instance, under economic difficult circumstances it is harder to maintain sales rates, while individual job performance may still be high. Moreover, while self-rated job performance may be a less objective indicator of performance than measures such as sales rates (Williams & Anderson, 1991), the measure of job performance that is used in the current study indicates an assessment by the employee about their performance on the job (see e.g., Bal, Jansen, Van der Velde, De Lange, & Rousseau, 2010b;De Vos et al, 2003). Subjective performance measures are valid for the current study.…”
