At my last workplace, we officially got two 15-minute breaks per day, one before lunch and one after lunch. Now this was at a non-regulated, non-union, private company and we were salaried employees who routinely showed up early, occasionally stayed late, and many of us were still checking (and responding to) emails and tickets, fixing things, etc. from home at all hours of the day and night. This was not a scenario where we had time cards or where everyone worked exactly 480 minutes per day or where being away from your desk for a few minutes had any negative impact on productivity.
Over the course of some years, a group of smokers had aligned our patterns so that we'd break for a quick smoke at 9:30, 11, 2:30, and 4. We kept it legit, it doesn't take 7 1/2 minutes to walk outside, smoke a cigarette while chatting, and walk back in. No one was taking four 15-minute breaks. Eventually HR sent out a warning to everyone who was "abusing" the break policy by taking two quick breaks during every 4 work hours instead of one 15-minute break.
So we shifted to taking our allotted break once before lunch and once after. And we used every last second of those 15 minutes, every time. We'd wave at the cameras on the way into and out of the building and one of us would always keep track of our remaining time on their watch or their phone. Guess which folks stopped showing up at work 20 minutes early, staying late to finish things up, leaving our email clients open and monitoring work emails 24/7, and handling shit outside of business hours? Guess which folks stopped bringing their lunches and eating in 10 minutes at their desk, and started taking their full lunch hours offsite every day?
Somehow there are still plenty of employers who just don't understand that if you treat your employees like a bunch of kindergarteners, you're not going to get things like "loyalty" and "amazing work ethic" and "110%" in return. No, you're going to drive away good talent, and with that talent will go many years of your institutional memory. And you deserve to lose it.
By the time I was out of there, we had a running joke that they were probably keeping records of anyone who took more than 2 minutes to take a shit. I suppose it's a function of HR feeling a need to justify their own existence from time to time. That company is currently advertising for an HR director, a little bit of schadenfreude to end my night on a pleasant thought...
