I am pretty sure that in our current contract profit sharing is not garanteed. Yes, last year and this year we will be well over 15%, but I remegmber getting 2-3% my first couple years here. In this new deal it's a guaranteed 10% plus the ability to get more on good years. It's simply a way better deal. The profit sharing is changing regaurdless. By voting no, you will only loose out on more holidays and a base pay increase. At least take this for now, and keep negotiating. The only way it's a pay decrease is to not take it.
