Hog boards were established over many yrs , & true it helps the junior man or low seniority but at some time later you may want to be on extra board & not have bid & that board makes it harder to keep a consistent pay check & your won't want to kill yourself to get back in also be careful what you wish for the ones who have implemented this found out they will cut your board(master) in half or less, you are making $$ now but after you won't have a job , some job is better than none, file the 4 week average grievance
