5 guys followed runs from New Orleans to Jackson Ms. with the full expectation that "If a senior feeder driver elects to take a job which has been transfered out, the displaced employee(s) will fill the jobs vacated by seniority until the next bid." First week we got to Jackson a run was suddenly cut so that a "bump" could start with the intention on one guy bumping one of us off one of the runs we followed. Second, run is having start time changed to declare it a new run and put up for bid. Bottom two guys are just being told the they will be bumped off the runs they followed just because Jackson has two drivers that have more senority than they have. In New Orleans, when guys have followed runs, they have remained on those runs until the next bid as per Article 48 of the Southern Region. Comments? Suggestions?
