Hard to say how to tell fact from fiction in the workplace...I was the target of some unfair targeting from others. Rather than stick it out to find out what was up, I gave in to their nonsense and quit the job. I shouldn't have...so, just go there and pay attention to your work (which is what I should have done)...in my situation, there was an active, documented campaign to get me out - a nitpicking, backstabbing place...but it was a large organization. If your employer is a large employer, then find the pockets of support and stick with it. Just my opinion...
