I did on-call duty for about 5 years, first as a developer and later as a product manager. I reliably got an extra 10-20% of my salary in compensation and did not really mind doing it.

We received a fee per week and a fee for every incident (150% normal hourly wage). There were between 0 and 10 incidents outside of office hours in a week. Most of the time 0 to 1.

Even though it was part of the job and the compensation was fair, the only thing I miss about it now is the money ;)
