Where have you seen this? Curious. PM/DM me kindly if you have an e-mail or such.
It’s my understanding that MEBA & MMP are looking to reduce the amount of crossover (pass-thru) between unions. There is some kind of potential agreement to reduce the number of MEBA mates.
It seems foolish for MEBA and MMP to compete for this separately after the SLNC contracts. It is a symbiotic relationship.
