Darden Restaurants is threatening to do the same thing.
They forgot to mention they haven't had full time employees since the Bush days.
I just got in a discussion with a buddy of mine about Darden. I asked him if he ever worked in a restaurant, and of course he never did. I told him restaurants have been doing that since the late 90's-early 200's, when I was a bartender. There is a reason all restaurants work weeks end on Monday or Tuesday. Those are the slowest days and if you have too many hours they send your ass home. I told him most tip employees work off the clock a lot of times because they don't give a shit about the 2 bucks an hour. The managers look the other way, since it helps their bottom line.
