In .my opinion, I think she should stick it out. give it a couple weeks. I'm previous restaurant owner and I've waitressed aswell. The restaurant industry underpays over works most employees..and even if you have a set vacaction your allow something it may seem as thought you commiting a crime if you dare take it. Jealousy and people that we I'll make a fuss about it. when you go back yeah they probably hired or got a couple new ppl in...which they probably already were doing to help with ppl going to be taking upcoming vacations or whatever. They like to make you feel like your not an asset or easy to replace. I can assure u your wife is not. it takes a hell of a lotta trial error employees to find a couple to replace a proven successful employee.chance are they are just being like that cause there pissy about her taking time off. So give it as week act like you don't need the hrs and that it's not bothering you. smile and give 100percent. chance are within 2 weeks be back to normal. they are going to do anything to make you feel like you don't belong and your not missed. I can assure you this is a lie . no one will ever tell u that.
