Our store can be flakey at posting the schedule in a timely manner. I will be calling the union next schedule if they don't get their acts together and publish the damn thing. What do you do in this scenario?

A. Show up to work during your normal time frames if you work a repetitive schedule? or B. don't show up at all because you're not on the schedule. C. Call the union, show up for your standard "shifts" then file a pay grievance?
