Many years ago my first job was part time night fill at a major supermarket (starting with W). The night fill boss would (illegally) sign our time sheets instead of getting us to sign them. (we were all teenagers at the time and didn't know our rights). The boss would always sign us off early, ie at 11pm would announce, "you are all signed off for 11:30", this would be done with the full knowledge that there was no way we could finish by that time. We would work our butts off for the next hour plus and be underpaid for our efforts.
After many months of regular work I took a week off (unpaid).
It seems they continued to sign my time sheets while I was away.
The following week one of the bosses said to me, "don't you want your pay?" For once in my life my brain was faster than my mouth and I replied, "didn't I pick it up?" (these were the days of cash payments, folding stuff & coins).
He handed me the pay packet and then went through the entire store, telling all the staff what an idiot I was because I didn't pick up my pay and had forgotten it.
I quitely worked away, happy that some of the unpaid extra hours had now been paid....
