In response, FIFA said it was "extremely disappointed by the increasingly divisive and contradictory tone adopted by FIFPRO leadership".
The governing body said in a statement: "The game deserves unity, not division. Players deserve action, not rhetoric. FIFA will move forward together with players and those who really want the best for football. It is up to Fifpro to answer this call."
Despite that, players such as Manchester City's Rodri has threatened to go on strike as many have been left exhausted by the increasingly demanding schedule - something that was exacerbated with this summer's Club World Cup.
Moreover, FIFPRO were reportedly not invited to a key meeting that FIFA held on player welfare earlier this month, and this has happened before, too.
