It's a learning lesson for all junior drivers. In a nutshell, you are either scheduled or laid off, there is no third direction. Before you leave on your last scheduled day of work, the next weeks schedule must be posted. If your name and start time(s) are listed, you are required to be at work for those shifts. If your name is not present, you are laid off and should make your wishes known before going home. The company would like to think there is a "on call" list, but that just doesn't exist. If you are scheduled and the company attempts to call you off, ignore the call, show up to work, ask to be placed to work and if no work is available, go home and file for the appropriate guarantee. It takes our building about 5 paid grievances before they take responsibility for the schedule. Happens every spring and fall when vacations dip.
