Many. 1) Mandatory return to office is terrible. In a "what have you done for me lately?" culture and no work/life balance, now they ask that we spend hours commuting and we can't get our work done in traffic 2) If you were hired remotely and want to keep that, you won't be considered for promotions if they can hire someone that goes into an office. I've seen this happen to my colleagues 3) None of your feedback will go anywhere. We don't provide manager reviews. They are free to behave poorly without consequences even if you go to HR
