Do others not generally get extra pay for the time on call?
I have the enviable situation where I am on call for half of every month, I get paid significantly extra for this, and there's maybe 1 emergency call per year.
My last several jobs the extra pay has been a small phone stipend, and perhaps a very small token sum (maybe $50 for the week).
The only time I made significant money on call was early in my career as a contractor.
Nope. Amazon, for instance, has their engineers on call in a variety of roles with no additional pay.
Salaried tech employees do not get extra pay for being on call, generally.
