Fair or unFair?

After a long wait of several months, it's that time of the year to give out our incentive for using foreign settlement on guest's credit card. This time, we each got 80 dollars worth of Takashimaya Voucher. Happy but... heard some indigestible news. It seems, my superior wants to use a little part of our long accumulated incentive voucher to pay for an long overdue outstanding amount that certain guest did not pay. And the manager who was suppose to follow up did nothing. 2 months have gone... now, they want to use our hard-earned incentive to pay off someone's mistake. Yes, it's important for us as a department to cover for one another but when only certain people get protected, it can become very political. My dept is split into the C people and the S people. The latter gets forgiven for any mistake made. Maybe just one or two sentence of nagging? Then, there's another 2 very obvious group of people, the 'work till wanna die' kind, and 'pretend to act busy' kind. It's getting harder and harder to work each day. I desperately want to go back to Operations, and stay far away from all these good for nothing higher management people. The work load is so unevenly distributed, it's pathetic, even my pay doesn't do me justice. Much less for the people at the reception fighting for their survive. Heck... let's go on strike.
