Iam currently a 22.3 full-time combo employee. I have been a 22.3 employee for the past six years. I just switched to a different combo job preload load/unload with exception scanning. My question is Management has told me that I can only load/unload. My bid job is my combo job I can't move to a another job on preload. For example if I wanted to go sort in the sort isle,damage cage,small sort,first responder,spa packages for the pas system,clerk,loading brown cars for the drivers. Why after 11 years with this company can I only load/unload trucks? Management claims that ''I can't have an easy/easy job''.Why there are plenty of examples of other combo employees working two easy jobs.I have gone to my local union and informed them that 90% of the preload 22.3 employees are not doing there bid combo jobs.Almost all have easssssssssssssssy/easssssssssssy jobs.The local union told me to file a grievance.What part of the contract should I look in? How do I get the employer to recognizes the principles of seniority shall be given prime consideration in everyday operation?Help?
