Most Doctors are not on call. Police are not on call. Firemen being on call sounds unbelievable from a union perspective but many volunteer fire departments exist.
On call for a week every 8 weeks is a lot different to a once a year event like a manager getting a call that a break-in happened at a store.

Firefighters in the US typically work 24hr shifts, then have 48hr off, then repeat[1]. You could say they are 'on call' during that 24hr shift, of course they don't normally fight fires every minute of it (luckily), much of that time is spent doing things in the firehouse like maintenance, eating, etc.

There are plenty of jobs that are not on call. Lots of enterprise positions do not require you to be on call. If you work on a site that requires 24/7 uptime, why is it so hard to accept that engineers have to be on call?
