Friends at Work

I have come to the conclusion that making friends at work, and especially trying to be friendly with your supervisors, is a huge mistake. I have attempted to be an easy-going, 'real' person who can be and is very professional at the times I need to be. Apparently this isn't what my supervisors are looking for, despite the 'family atmosphere' they try to achieve and maintain, and tout so much. I just received an email from my immediate supervisor regarding, among other things, my attitude. Apparently I can't tell when I'm supposed to switch from person mode to professional robot mode, or when I'm supposed to be which for which supervisor, or how to tailor my comments to their individual personalities, moods and daily issues. So, I'm not going to try anymore. I'll just be the professional robot at all times, lick their boots like a good little slave, and try not to think about work AT ALL the rest of the time (despite the fact that many of the things they praise me for are things I think about while I'm away from the office). If that's what they want, that's what they'll get, but I hope they realize that all of my company loyalty is now gone, because I think there are some places I could work and be myself without having to worry about offending one of my supervisors just because I have a better idea, or one that would work as well but is easier to implement; I also imagine that I might receive pay more appropriate to the work I do. As soon as I get a job opportunity at one, I'm gone.
