Workplace Rant....What to do?? Kinda Long...Sorry

I've been kicked around for over 20 yrs. I have learned that 90% of the time it is best to keep all your thoughts to yourself. I used to get vocal and talk back, but it didn't do a bit of good. Jobs are not easy to come by now, so don't record, don't turn the supervisor in, just do your job the way you know it should be done. Eventually you'll have 35 years in, and you can retire.
