You work for a company and your manager mentions to you that he knows that you want to be promoted. He promises that he will put in a good word for you with upper management if you agree to lie about a coworker. He dislikes the coworker and wants you to lie and say that this coworker is rude to customers so that there can be a reason to fire this coworker. This is best described as an example of:

a$.$ bullying

b$.$ harassment

c$.$ corporate$/$institutional bullying

d$.$ retaliation
