Pager jobs at smaller companies are often not on shifts. Larger companies are usually much more realistic about it. Larger companies tend to give you shifts, along with the better compensation and more realistic expectations, at least in my experienice.

Legally, as an exempt employee, at least in California, my employer is in the clear. Hell, I believe they do it to hourly workers, too. I have worked in the computer industry my whole life, but I am told that it is not uncommon for minimum wage jobs to insist you come in at unexpected hours to cover unexpected events.
