I worked at a company where I learned after joining that we were mandated to stay until 6 PM. Yet with my particular job, I was on-call at night (and sometimes was called and would work through the night), had to do weekend work etc. Everyone else worked 9AM-6PM, I had to work the extra 5 hours a week, for complete bullshit corporate purposes, plus all the other hours that were specific to my job. Complete bullshit. At previous jobs I was always there at 6PM anyway, but being forced to drove me crazy. I eventually left.
