Our DON tells us that employees are entitled to a a break 30 min per 12h shift with two 15min breaks "if possible" The 30 min is unpaid, so nurses can leave the building, however they do not dictate WHEN they get the break. Nothing says that they have to get it when the cafeteria is open.
And... if they get a break at 0530 that it still counts, even if they have not even had time to pee before that. We "try" to accomodate them if they need a particular time etc. But, she says that is the letter of the law. And in Canada you can be called off your break, so get it in 6 5 minute batches, and still not get the benefit of no break OT.
I don't think it is fair or right, but that is the argument when someone wants to say, group all their breaks and sleep for an hour- that we could be SO much stricter according to the law. That they should be aware that getting a "full" break, or getting to the cafeteria during the lunch hour is actually a favor.
