Let us know who this employer is. They can tell you what to say, but they can't force anyone to shop there. Merry Christmas.
why, should we not shop somewhere because they're trying to be politically correct?
This goes back to the other thread about why other people celebrate xmas that aren't christian. If you guys don't want other people celebrating it, then Happy Holidays is the way to go. If you think it's an American holiday, then by all means...say merry christmas! But shove it up your ass if you don't want other people celebrating it but still insist on telling EVERYONE merry christmas. You can't have it both ways. It's either a religious holiday, meaning it's inappropriate to make it generic, or it's an American holiday, which means being generic is A-ok.
It's actually funny how silly you people can be about something like this. Nobody tells me "Happy Chanukah" when I'm out shopping. Does that offend me? Not in the least. They tell me "Happy Holidays" and I'm just fine. If they say merry christmas...well I couldn't give a rats ass, but it's rude for them to not be accomodating (and if it's a waitress, I'd consider reducing tip if I'm borderline on the rest of the service provided). So all of us Jews, Muslims, African Americans (Kwanza), and other random religions...we don't care if you don't say happy hanukah, jolly kwanza, or whatever...yet you guys freak out when someone doesn't wish u a merry xmas? Get over yourself!
But to the original topic...if your employer tells you to do something, you do it. If you don't want to, you can either argue with them or find yourself a different job. It's their business, not yours. They're the ones losing customers and money, not you. So you do what they tell you to since you're nothing more than their peon.
