Guarantee the higher ups get their vacations, food, bathroom breaks, etc., whenever the bleep they want them. And how you have to cut your vacation time short, because there's a crisis at work. But, ask for a raise, and your lot is a dime a dozen on the streets. Oh, and don't you just love it when they tell you that they "can do your job better than you can". I've said, "prove it, here's the keys". Was told after that, that I had a problem with authority (boss). What I have a problem with is incompetence and lack of leadership.
The extra 15~20 before and after is called "face time", but don't you dare clock in/out before or after the appointed hour. Gotta prove your heart beats the company colors and other assorted BS.
Been there, done that, got the T-shirt, T-shirt worn out, don't want another one.
I've been self-employed for the past 10 years. I learned a wonderful new word that you can't and don't dare utter if you are employed. That word is "No". Amazing to me is the respect it gets from others. And I've found that if I have a problem with the boss, then I guess it's was really me and not the boss!
