Stupid rules handed down from above that change when it’s beneficial for them. Ex. We’re not supposed to be worked more than 6 days straight until they need you then that rule disappears. When I was hired I was off Sundays and holidays which was important to me. Suddenly with no notice I’m required to work Sundays and holidays with no extra compensation. Seniority means nothing, work record means nothing. You can give your all, cancel appointments, drop everything, miss family functions, work yourself practically to death and a new person in the first 90 days makes same as you and you have to rotate schedule with them. I never had called off sick in 5 years, 1st time-denied because a new person didn’t want to work.
