The Corkman, who is reported to earn in excess of £60,000-a-week, will back any strike action, because he believes that the PFA are important in helping the players who are not as well off as he is.
"It is important that we stick together," insisted Keane. "People have to know what the PFA is all about. Premiership players are well rewarded, but what about those in the lower leagues, past players and young kids who have their careers ended by injury?
"I spoke to a friend last week who had to finish early and the PFA have helped him with operations on the injury and courses to provide him with an alternative career.
"Nobody wants to go on strike, but I will be 100% behind the union no matter what they decide to do."
