HR won't do anything to help you get unplanned time for a medical necessity without using one of your call offs if operations declines your request for PTO
Depending on the product you support, you're taking calls for something that is in a constant broken state. With certain products being forever broken, when you get cross trained you have to manage ticket queues of well over 40 as well as take calls for 8 hours a day because of hold times leaving you with no option but working overtime to get things done. If you don't keep up with everything, your supervisor will message you constantly asking for updates on tickets despite being on calls.
There is no communication between leadership and Tier 1. Most things are kept secret, and it makes the floor feel like nothing is being done - especially when things get progressively worse.
If leaders cannot relate to your situation, they will talk down on you and make you feel like less of a person because you don't meet their description of "normal"
