I wonder if the writer actually has a family or some sort of life.
Wouldn't miss the birth of any of my kids or any other family event for the job. We're not saving lives here, it's just another job, mate. Things can wait till next morning, no one's going to die.
Anyway, I quit my previous role, a 9-5 slavering IT sys admin job. I hated the atmosphere and being sitting at a desk all day. So instead, I didn't quite change careers, I changed to a free-lance engineer and I just go to see clients at different locations and do a lot of remote work too. So, you don't have to HATE I.T. to leave the job, you have to identify other factors that contribute to your desire to leave the job. Whether it's the location, the users, your boss, incentives, family, etc. You can still remain in the industry, just change the focus.
