Which of the following is an organizational factor that increases illegitimate political behavior?

Akimi4 [234]

Answer:

B) high trust zero-sum reward practice

Explanation:

Zero sum reward practices are generally not that successful since usually only a few are benefited while several people are left out of the benefits, or lose. If someone gains a benefit at the expense of others, it will always cause friction within the organization. That friction can lead to illegitimate political behavior, which is behavior that breaks implied rules. The regular "losers" in zero sum reward practices may be tempted to break the rules or cheat in order to obtain the benefits.

For example, if the same person is always selected as the employee of the month, his/her "losing" coworkers may start to sabotage his/her work.
