generally men are easier to work for.
but, i've had bad bosses of both sexes.
one time my female boss was bad, but her boss, a guy, was badder! yes, badder.
they fought like a woman and man in a marriage in a domestic dispute at work! yelling and screaming at each other in public. si.
Sonds like the meetings where I currently work.
Lots of screaming and shouting, you'd think WWIII was starting.
By the end of the meeting everybody has reached a concensus, lots of smiling and joking.
Weird, but effective.
I've had both male and female bosses, and some of the men were idiots. But that just made it easier for me to work around them and do what needed to be done. They were never offended if I was better at their job than they were; they were glad to have the help. I have found that obviously gender had nothing to do with whether or not one can be a good boss. It does come into play, I think, when problems arise or competition is a factor.
I had one really great female boss, but she was tough as nails and dealt with things verrry cut and dry. She had no tolerance for idiocy, cattiness and the disregard of rules. In essence, she was a good conservative.
