I'm afraid I am.
It is in my nature to expect everyone to act in the best interests of everyone else. I never expect that others will intentionally cause harm to another in a willfull and malisious act.
A few weeks ago I confided in a co-worker a mistake I had made and had to correct on a project I was working on. I was able to correct the problem before it became a *big* problem and all was well, which is why I felt safe in telling this person.
Nope... He screwed me. He made sure my Supervisor’s, supervisor’s, supervisor knew what happened just before the mid-year reviews were done.
I'm afraid I'm just going to have to be more careful with whom I share my failings.
