answer:If I am following the scenario correctly, I don’t understand why other co-workers and your supervisor would encourage you to do PTO co-worker’s tasks the way she trained you if they want to prove her failure. Wouldn’t it make more sense to allow you to do these tasks in your own way and prove that she is insufficient at her job? I worked for the same company for 25 years in various positions. This type of situation would crop up occasionally. For awhile, it was common for an employee to be shuffled to a different dept. or location based upon fictitious rave reviews from a supervisor that just wanted the employee gone, but didn’t have the gumption to terminate their employment or find a better fitting job within the company. My advice is to stick to your morals, avoid the gossip, and keep your supervisor in the loop objectively.
