This guy probably is the tech but is wanting to spend more time with his family or something.
Probably settled down too fast and can't get a better job now. My advice: don't settle down and quit using your wife and children as excuses for your career failures because they'll grow to hate you for it.
OR, if you want to have a family life, don't take a job that requires you to do stuff that's not family-life-oriented.
That's the route I've taken - no on-call phone, no midnight maintenance, no work-80-hours-get-paid-for-40 bullshit. Pay doesn't seem that great, until you factor in the wage dilution of those guys working more hours than they get paid for. Turns out, hour-for-hour I make just as much as a lot of the managers around here, and don't have to deal with half the crap they do.
The rivers sure have been nice this year... and the barbecues, the lazy evenings relaxing on the porch, the weekends to myself... yea. I dig it.
