I've been a 4X10 cover driver 3 times, no extra pay, and a swing driver twice, a little extra an hour, less than a dollar. Cover drivers are considered regular couriers, swing drivers are a different classification. The catch of being a swing is when they try to bid on a courier rt they are in Priority Group 2, which makes it difficult to get out of being a swing once they have you there. The first time I became a swing was in '99, given just 30 cents an hour more and was not eligible for the general raise that year as I had already been given a "promotion" and a "raise" becoming a swing. When I transferred out to become regular courier again they took over a dollar away from me.
