In their share issue prospectus, Rangers confirmed that PFA Scotland had raised the claims, which are to be "robustly" defended, and that former Ibrox players Sone Aluko, Kyle Lafferty and Jamie Ness have raised constructive dismissal claims.
The three players were among nine who refused to transfer their contracts over to Green's company, which bought the club's assets and business after oldco Rangers, now called RFC 2012, were consigned to liquidation in June.
Amid much confusion on Monday night, Rangers captain Lee McCulloch was the first player to distance himself from any employment tribunal via his Twitter account. A PFA statement explained the basis of the claim for a Protective Award "raised in the name of PFA Scotland only", saying that administrators Duff and Phelps "failed to enter into any consultation whatsoever with the players and PFA Scotland".
However, the players' union say they will drop their claim if Rangers abandon their breach of contract proceedings against their members, which will be decided by the Scottish Football Association.
But Green shows no sign of backing down in his own statement, which read: "The fact that many of the supposed 67 players are still at Ibrox and have indicated they have no part in this action begs the question why it is being raised at all. Further, it appears that a number of players whose contracts were due to terminate at the end of last season and who were never in line to transfer under TUPE have been included in the numbers.
"Also, a number of former players have already signed agreements with the club waiving any right to participate in this claim. In reality, we are talking about six players who have some form of dispute rather than 67.
"Rangers fans will note how the club captain Lee McCulloch and a number of other players have quickly dissociated themselves from this action. I have also had the father of one player calling, quite furious that his young son has been attached to an action he knew nothing about.
"PFA Scotland has confirmed as much in its statement earlier. That statement confirms that the failure to consult claim apparently lodged for the benefit of 67 players will be withdrawn if the club's SFA damages claim against the six players is dropped.
"The purpose of the failure to consult claim is therefore not to safeguard the rights of the 67 players but to attempt to persuade the club to abandon its legitimate pursuit of compensation from players who, in the club's view, walked out on their contracts of employment."
