Employees who are envious of their fellow workers often exhibit a decline in job performance. Research published in the Academy of Management Journal (August 2019) investigated whether workplace envy can also have positive outcomes (e.g.. learning and/or advice seeking from the envied employee). Data were collected for 52 sales employees of a cos- metics company. Initially, the researchers fit the model, E(y) Bo+B+B2x2 + Bax, where y = Advice seeking level (7-point scale) x = Envy towards fellow worker (7-point scale) x2 = Core self-evaluation (CSE) level (average of 12 7-point scales) x3 = {1 if envied target is a friend, 0 if not} a. The researchers theorize that the more envy exhib- ited towards a fellow worker, the more the envier will seek advice from the envied target. Based on this theory, is the value of B in the model positive or negative? b. The researchers also theorize that the lower the CSE level, the less the envier will seek advice from the en- vied target. Based on this theory, is the value of 2 in the model positive or negative? c. Finally, the researchers theorize that if the envied target is a friend, the more likely the envier will seek advice from the envied target. Based on this theory, is the value of 3 in the model positive or negative?
