Your mental health decline and your burn out is imminent. The hard work is not paid off and unlimited PTO is constantly denied when you ask off far in advance. Managers ask if they can help you. When it comes to it, they will avoid any work and push it off on you once again. Be prepared to be gaslit on your weekly one on ones - there is always going to be something to hammer you and criticize you on. Please, for your own sake, don’t do it. Love yourself and find a different company to grow with.
