A friend of mine is miserable in his job because of one person, his immediate supervisor. He likes his job, but just can't take it any more and is forced to look for another one in a not-too-friendly job market. We have a few float pharmacists in our system who no one wants to see coming. They are either rude and confrontational or hopelessly disorganized, and some of our techs get almost physically ill at the prospect of working a shift with one of them. In my pharmacy career so far I've witnessed several situations where one person has been allowed to wreak havoc on an entire department -- that one person makes everyone unhappy, and the gossip and the behind-the-scenes eye-rolling goes on day after day and creates a crummy work environment.
I marvel at how these people came to their position of 'power' -- to impact so many people just on the basis of their personality and yet remain untouched and oblivious. There never seems to be a solution, and supervisors are reluctant to listen to complaints that are really just 'personality issues.' We all gotta get along, but I wish some people could get with the program just a little more.
With that, I'm headed off for a few days vacation!
