讲座内容:Overweight employees are viewed as lazy, slow, inactive, and even incapable. Even if such attributes are false, this perspective can seriously undermine others’ evaluation of their work performance. The current study explores a broader phenomenon of weight bias that has an effect on weight change. In a two-wave, two-source longitudinal study with a time lag of six months, employees’ weights were measured using the body mass index (BMI) ranks and were found to undermine their supervisors’ evaluation of their performance at Time 1. Supervisors’ perceptions of employees’ weight change after six months notably altered their evaluation of the employees’ performance at Time 2, especially following low versus high Time-1 performance. Meanwhile, we found moderating effects among different levels of supervisors’ anti-fat bias as boundary conditions for both the weight-performance relationship and weight change-performance alteration relationship. In particular, supervisors’ anti-fat bias strengthened the negative relationship between employees’ weight and performance evaluation at Time 1. Similarly, the interaction between the Time-1 performance evaluation and the impact of supervisors’ perception of employees’ weight change on the Time-2 performance evaluation was significant only if supervisors held a stronger anti-fat bias.
