No, we don't typically do that. Generally speaking, an employee will work some additional time during the course of each day in order to be able to have a day off once every three weeks or once every four weeks. In some instances it's once every two weeks, but my sense is that it's more typically a day off once every three weeks or once every four weeks. So they add just a bit of extra time to each of their work days in order to be able to do that.
We also have what we call leave with income averaging. It has to be preplanned, and it has to be done with the approval of the manager. But employees might decide they want to take six weeks off in the summertime, so they'll plan when they want to take that off, and then fundamentally they take a reduced rate of pay during the course of the year so they still get some pay during that six-week period when they're off. And again, it varies a little bit by region, but nationally last year about 9.5% of our employees availed themselves of that type. And they do it for personal reasons. It could be for elder care, for children, or just for having extra time off to rejuvenate.
