That sounds miserable :(

In a previous position I was asked if I was willing to be on call, but it was optional. I accepted because the terms were good.

If I was on call the requirements were clear - No alcohol, and a 10 minute response time 24/7.

In return, I got a bump in my paycheck for weeks I was on call, no matter whether I was actually called or not. And any time that I did end up spending on support incidents I was eligible to take back out of normal hours at time and a half. So if I spent two hours on support in the middle of the night, I could take three hours off the next day.

It was a respectful arrangement that made me feel positive about the company and management, and I wish all companies did it that way.
