Here's a synopsis of an actual case that we lost:
One of our location sales managers attempted suicide. She was provided with 12 months of FMLA leave. Upon her return, she simply was not the same person. She was no longer able to generate sales and meet goals. It was decided to put her on a performance improvement plan. The Vice President of her department drove to her location (an all-day drive) to discuss the plan with her. She called out on the day of the meeting, obviously greatly aggravating this VP. So, a two day trip turned into three days before she could be counselled on the plan and provided with assistance, guidance and expectations of meeting goals. After a few weeks, she was not progressing toward goal, and continued to experience attendance problems. We fired her.
Despite hard data showing that she was not achieving sales goals that she routinely used to achieve.... despite hard data showing that she was under performing all of her peers at other locations.... despite hard data showing she was making no progress toward achieving her goals... a jury took pity on this pathetic individual and awarded her a six-figure judgment, making her the richest person in the county.
The system sucks. Sorry you can't see that.
