> I mention on-call duty because it is “peculiar” in that the only other profession requiring this kind of responsiveness is doctors My only advice to this person is: - talk to someone who does customer-facing tech support in your own company - never take a job in customer-facing tech support
I worked in high volume manufacturing where process engineers could be on-call 24/7-365 unless you explicitly asked a backup to cover you during a vacation or weekend. Depending on the part of the process you owned, that might mean a middle-of-the-night call a couple times a month or several times a week. No human lives on the line, just lots of money.
