About to quit my job....I don’t get even a single chance to pump while I’m here...from 8-5 venting so skip if u don’t want to hear it lol

I don’t get a break so I don’t get to pump. I asked the lady if I could lock the door and put sign out she said no have my coworker cover me. What she doesn’t know is that he doesn’t have time. Our location has hardly any workers now. So I don’t get to pump. So far I still get about 8-12 ounces in the morning and when I get home after feeding him. I don’t think my supply has decreased but still. They already messed up my insurance. They didn’t have me sign some paper when I signed up for short term disability and now I’m still waiting on my money. They had to appeal my case since I’ve been paying all this time for the coverage and they are just now telling me they needed a paper from me. Now this. I’m a little over. The only time my son had formula(twice at 2 weeks) he spit up like crazy. I’m not changing my milk supply going way down because of a company who doesn’t care about their employees.
