In the olden days when my phone would ring, I had no idea who was calling. Sometimes it would be my boss calling me in to work. I always appreciated the extra money - heIl, I was happy to have a job - so I'd go to work. 
The calls usually came as a result of a coworker calling in sick or some other unexpected vacancy. I was also willing to work longer hours. Time and a half pays better than time at home. I somehow managed to get my laundry and necessary shopping done. As I recall I even managed to have fun in my spare time. 
I was always faithful to my employer and was rewarded every week with a paycheck and was usually given time off when I needed it - or wanted it.
The idea that employers are all ogres to be loathed has had a negative effect on worker produtivity, IMO.
It's too bad that more miserable, downtrodden, underpaid employees don't leave the heIl they're living and start their own businesses as Amber has done.
