Of several female bosses I had, I can assure you that none were "dicks". Though most of my male bosses stepped on theirs. The woman bosses were entirely reasonable at all times.
I can say I've had good and bad female bosses, and male ones.
two jobs back, it was the manageress who was rotten to the core, while the manager and owner was a nice guy, tough but fair. Mr previous job went though many different managers and bosses, the 2 female manageresses were okay, not perfect but nice enough, while the manager was a complete asshole and bully. All three of them quit while I worked there and some district managers came and went, but the worst one was the staff manager who stuck around since the beginning, and she was a tyrant to staff, shouting at them, even on the shop floor, a genuinely miserable bitch.
