My friend discovered at work that there was a "plan" by two employees to try and get her fired. These two individuals were trying to get people who were quitting to sign a paper that she was the reason they were leaving. These people did not sign, however, when my friend went to her manager about it, her manager confirmed that this was indeed the case. Now, the manager is writing her up for complaints by the two individuals for things like...not saying good morning when coming into the office. Would my friend have any recourse since the manager knew, and confirmed of the "plan" and now seems to be backing the "planners"?
