Answer:
The McCombs experiment demonstrated that employees are more likely to be promoted if they show hard work ethic, depsite the amount of skill they may have. In the experiment, they recruited 138 business school students to play the parts of managers and employees during six work periods: three before a hiring decision and three after. For each period, employees earned a fixed wage in points that was converted into actual money at the end of the experiment. For every period, employees chose what level of extra effort to put in, from 0% to 100%. Raising their efforts more than 20% would cost them points. After three periods, the manager decided whether to promote or hire from outside. The results were as follows:
Overall employee efforts increased up to 51%, peaking right before a hiring decision.
Managers promoted employees internally 54% of the time.
Average effort was 18% higher for employees who got promoted.
This experiment shows that hard work often leads to a promotion.
