Ruined Reputation

I've worked at the same place for many years. I had the same supervisor for all but the last few months - the best boss I ever had. She understood my position inside and out and trained me once and let me go. She didn't hover or micromanange.

The hierarchy changed, and I got a new supervisor. They didn't understand my job at all, made rules that got in the way of me doing my job, and decided a new employee was their pet. Then, they found out they were being transferred to another location.

As the ad hoc leader of my co-workers, I was in the way of the pet person getting ahead. For the last month of working in my location, they set about ruining my reputation with the manager. I didn't even know they were doing anything behind the scenes. In the last week of working with me, they changed my schedule. They put me down for a day I wasn't scheduled, so I wouldn't know to come in and would look irresponsible.
Luckily, I found out. Angered that it didn't work, they lied to my face about changing the schedule and accused me of changing it. That's when I realized something was going on. I didn't realize the extent of it, not then. I'm now starting to see it.

The boss has been convinced. I am lazy. I don't understand my job. I am a trouble-maker. The thing is, if you are labeled a trouble-maker just about anything you do to try to make that label go away makes you look like a trouble-maker. It's self-fulfilling. All my years of being a model employee, the position of the lead of my group, is all shot to hell in one month, and I never saw it coming.
I can't tell the boss they've been lied to. I'd just sound like a trouble-maker. I'll just keep doing my job. I don't think it will make them realize they've been mislead. I imagine any tiny failure on my part will justify what they've been lead to believe, while all my successes will be written off as chance - a bad employee getting it right every now-and-then.
I'm a little impressed with the person who was transferred. I never considered anyone could be that evil and do it so discretely and completely in such a short amount of time.
I've never been the 'bad employee'. I have no idea if there is a way out of the misdeserved title.
