Here in the West, we were the first to get Satrurday Delivery rolling. We new the company would need to hire more Cover Positions. If fact, they did. This then created more drivers. We have a Saturday extra work list for Full-time and a Monday sign up list for those that are Tue-Sat. The covers are scheduled cover Tue-Sat. This allows them to gain their progression and earn the rate through their 4 years. We also tell all our Monday-Friday full timers not to go home if their routes get cut. Forse the company to allow you to use your route bid language, that is , displace the low senior in your loop. Now, that makes the company either, let a route driver now displace a utility driver, who now will also possibly be blind on a route, or, have to allow the Senior route drive go out blind on a route and bomb. It has been a hard road. But, the stewards are very good here. They, make the company comply with the contract. And have also had routes put in. Not to mention, come summer the need for vacations that will put all the Tuesday-Saturday people on a 6 day work week. And the cover drivers being called in on Monday at top rate(outside cover language). So, looking at it, this will be the norm, and as an over 25 year Teamster, this is continued job security.
