I work anywhere from 9 to 16+ hour days. Overtime is mandatory in my job. But the horrible OT doesn't always happen and I'm not always busy. We used to work a 7.5 hour work day but as our company went 'global', that was altered to an 8 hour day (which is really a fantasy at least for me). I work at least an hour or more of overtime every day (and I don't get paid for it).
A close friend of mine works like 60+ hour weeks. This is the new North American corporate model. They've actually congratulated themselves on keeping expenses being down but increasing productivity. They do this by piling workload on people instead of hiring. It's month by month, quarter by quarter. Most companies are now about managing expenses. She and I are both burning out.
I want to be more like kairos, kaik, or joe.
