I filled a grievance last Monday for 9.5 violation. This is the first time I have ever filled a grievance in the 4 years I've been driving. For the last 3 1/2 years I’ve always been on routes since I know about 30 routes in our center. Magically on Tuesday after filling a grievance I was not put on anything and about 15 people with less seniority below me where working. I asked to bump and was told no bumping today. Eventually someone volunteered to go home and I ran their route. Should I have filed for retaliation? They also did the same thing another day later that week.
