Q: Who is eligible for membership in the Association? A: All players, managers, coaches and trainers who hold a signed contract with a Major League club are eligible for membership in the Association. In collective bargaining, the Association represents around 1,200 players, or the number of players on each club's 40-man roster, in addition to any players on the disabled list. http://mlb.mlb.com/pa/info/faq.jsp#membership Literally nothing, huh? I didn't know that he's not on the 40 man yet. Bryant doesn't have a MLB contract because he's never played in an MLB game so he is ineligible to be represented. And he won't be on the 40 man until he's called up. So, I don't see the Union's stance as strong but I am not a lawyer. It's the same reason that players can't be added to things like video games until they play in a game and file paperwork, regardless of their status on the 40 man, this is because they are not part of the union yet. For a player who has been called up then sent back down it matters but in Bryant's case it does not. I guess I just don't see the Union's end game here because the CBA is agreed upon by the Union and their lawyers and the players and teams use what they can. If the Union wants to renegotiate in the next CBA and put some language that is subjective with regards to milestones a minor leaguer has to hit and then require the team to call the player up then I could see them having a case. But again, I'm not a lawyer, I just don't see how the organizations will negotiate a way that will leave their roster decisions in the hands of an arbitrator.
