Not my experience when I was there. I worked 12 hours a day sometimes for 9 or 10 days straight without a day off and it was mandatory. If you didn’t like it, too bad. I finally retired at 58 last year. They were also very strict about being there off the clock for any reason. It was never allowed.
As a supervisor at a company years ago where over 25 hours per week was considered full-time (with full benefits - it was to accommodate a few specific positions), I understand why Staples does this. We had to do the same, and would have people pull all sorts of nonsense then hand in timesheets with 26 hours. They hadn’t done any work past 25; they had just screwed around, and we put a stop to it.
Anyone who has supervised full-time hourly employees understands that they are protected from the egregious abuse of “unpaid overtime” often heaped on salaried employees; we had to make sure they took their scheduled lunches and left on time to avoid having to pay overtime. Companies that failed to take these steps lost a lot of money in court after laying such employees off; when the employees could prove they had worked extra hours (often over the span of years), they were awarded overtime pay for it - and they deserved it.
It is illegal to “donate” work, off the clock
