You admit you worked a job for five years that "nearly broke you". You do understand that life is not supposed to be about how much punishment you can endure in exchange for money, right? There are ways to pay your bills that don't involve inducing physical and mental health issues?
When this is done to a child it's called "spoiling" them - for good reason.
If your calls were often at 4am and you had to work a normal schedule, it certainly does no good. Also, you are saying that nearly broke you, as if it's a badge of pride or something good...
So this being said, I agree with the GP - on-call sucks, but one week in four is not that bad. One week in five and it's fairly breezy. One week in three or less and it's pretty bad - you basically stop having an external life altogether. Like the GP, I also thought the article was a bit whiny. Yes, there were some truths in it, but whines like "omg, there is crunch time" make the author sound pretty self-entitled. Another whine was "not working for the same boss that hired him"... after six years in the company. Who could take such a complaint seriously? One of the more valid problems listed is the shifting of priorities every two weeks. That stuff is a killer - to morale, to progress, to development, to pretty much everything.
The OP's described situation sounds like it is hideously under staffed / resourced.
But it doesn't have to be that way; I have friends who worked at Sun (back in the day obviously) where they had approx 1 in 5 week rota, and always two on call at once (one primary and one secondary). And that with a typical 2-3 pages out of hours. A night and day difference.
It's called support hell for a reason - but what this guy's wife describes isn't extraordinary. It sounds like most mission critical support roles.
Out of hours support sucks, but yes, the reality is that you get paged, and you have to deal with things within SLA. It's hard, it's wearing, but one week out of every four is hardly intense.
I was on call for five years. It nearly broke me - but this article is just whining. Why take such a role if it's such a problem? It sounds more like his wife bashing him every time he had to do OOO work is what broke him.
