They start at the bottom of the seniority list (at least they are suppose to) and they put on the schedule for you to call in at a specific time the next day and at that time they tell you if your working that day or staying home. If you stay home, you are then scheduled to work the next day while the next man on top of you calls in the next day to see if he works or not. And they go on up the list till it reaches the top and they start over at the bottom. If you call in, and they need you to work, the next day you will call in again to see if they need you. You will be put on call everyday until you rotate off. They may have multiple guys on call. In FAY, they have been putting 6 guys on call at a time. They may rotate all of them, or they may only rotate half of them. They have been going so fast thru the list that the drivers who rotated on Monday, may rotate again on Friday. That sucks. Where the p and d drivers are rotated daily, our combo and linehaul drivers have been rotating one off every two or three weeks. give or take, but nothing like those in the city. Hope this helps.
