My last boss timed our coffee runs. He'd stand by the Keurig with a stopwatch app and make notes if you took longer than two minutes. It created such a weird, tense vibe that our best salesperson left for a less insane competitor. Tracking bathroom breaks is a whole new level of awful.
Three weeks in at my old call center job, the manager put a sign-in sheet next to the restroom with a column for "reason for visit." I had a kidney infection and had to go like every 45 minutes. He pulled me into his office and said I was costing the company $3.47 an hour in lost productivity. I quit the next day and found out later that three other people from my team did the same thing within a month.
