Because of the changing economy of the dotcom world UPS to keep business needs to work those days to keep our customers happy. If they schedule a shift it should be staffed by union people. The attitude of not me I am not going in will eventually kill the goose that laid the golden egg. I really don't feel sorry for the people being called in because I have worked under article 40 for the last 19 years and had to work every Black Friday, every Christmas Eve, and every New Years Eve for straight time. As a matter of fact I thank you because now that they schedule the whole sort on the holiday I finally get premium time (double in my supplement).Please go into work and enjoy the extra cash, maybe even order something on Amazon prime with the money,you will get it in two days! Peak will be over soon and management will be busting your chops to get off the clock.
