punch clocks for stickler cock sucker management is more counter productive than anything else.
My highschool and little after job I worked at was a punch joint too back in. We would rotate on who would come in on time, and punches all of us in, and the rest showed up a little late. Lunch time, same early dude punched us all out after the others have been on lunch for 10-20 minutes. then at the end of the day early guy left early, and tomorrows early guy stayed to the end and punched everyone out and was on early duty the next am. rotated it like clock work. we were smart too and the punch guy would punch 2 cards, take a piss, and punch the other 2 a min or so later so it wasnt obvious. never got caught it was gold!
