When am I guaranteed 8 hours of work at UPS?
Full-time employees who show up for their scheduled shift are guaranteed 8 hours of pay, with narrow exceptions.
Full-time package-car, feeder, and inside employees who report for their scheduled start are guaranteed 8 hours of work or pay under the National Master Agreement, with the exact language and exceptions (e.g. acts of God, picket lines) spelled out in your supplement.
Part-time inside employees typically have a separate, shorter guarantee (commonly 3.5 hours) defined in the supplement. If UPS sends you home early without meeting the contractual conditions, that's a guarantee grievance — file it through your steward. Ask TeamstersGPT with your supplement selected for the exact guarantee in your classification.
