I am the lead on a team of 5 and technically we have an on call rotation but it is rarely used. In the last 3 years I have been called after hours a total of 4 times and TBH it was usually due to an AWS outage which resulted in us saying well let’s see how long it takes for them to o restore services and then someone run a safety check to make sure shit is normal.

For that I make $120k, have unlimited PTO, and work from home.

I know 2 people who wrote COBOL code for some major healthcare systems a long time ago and they came out of retirement about 5 years ago to update/convert that code. They made six figure salaries working from home to update that code.
