That Evil Wal-Mart Is At It Again

Yesterday was payday at Wal-Mart and thousands of hourly employees employed by Wal-Mart received their quarterly bonuses. At the store I work in, the bonus was for about $440 for full time employees and a little less for part time employees. That came to about $20,000 in bonuses for the store.
Not all Wal-Mart employees got the bonuses- if their store did not meet expectations and salaried managers don't get bonuses- they get one lump sum after the first of the year.
So, bonuses for hourly workers, various forms of health care available, matching funds to purchase Wal-Mart stock, 10% discount on general merchandise (non-food) items, 10% discount at some private colleges, 401K plan and so many more benefits.
And why do we need a union?
