I got word last week that my planned stop count is going up another 10 stops. That's in addition to the 15 stop increase from 6 months ago. Today, I did the 120 stops that they wanted me to do. I ended up working 9.75 hours + 1 hour break. It was a typical day, no major delays in delivering. That amount of work now prevents me from spending any meaningful time with my kids during the work week. Our contract mentions excessive overtime and requires UPS to plan an 8.5 hour day (9.5h with break). I'm planning to grieve this. Our building isn't known for grieving parts of the contract, and this would be my first grievance. Is there anything I should know before proceeding?
