The European Leagues – a body representing 39 leagues including the Premier League – has filed a complaint to the European Union's antitrust regulators.
The move comes amid controversy regarding the calendar, with the first edition of FIFA's expanded Club World Cup set to take place in the United States next year.
Last month, Real Madrid coach Carlo Ancelotti suggested the European champions could boycott the competition, only for Los Blancos to subsequently confirm their participation in a statement.
FIFPRO launched legal action against FIFA at the Brussels court of commence in the ensuing days, claiming the decision to schedule the Club World Cup had violated players' rights.
The union has now joined a number of leagues in taking the issue to EU lawmakers, with a joint statement reading: "The international match calendar is now beyond saturation and has become unsustainable for national leagues and a risk for the health of players.
"FIFA's decisions over the last years have repeatedly favoured its own competitions and commercial interests, neglected its responsibilities as a governing body, and harmed the economic interests of national leagues and the welfare of players.
"National leagues and player unions, which represent the interests of all clubs and all players at the national level and regulate labour relations through collectively agreed solutions, cannot accept that global regulations are decided unilaterally.
"Legal action is now the only responsible step for European leagues and player unions to protect football, its ecosystem and workforce from FIFA's unilateral decisions."
Madrid and Manchester City are among 12 European clubs to have booked a spot at the first 32-team Club World Cup, due to their recent Champions League successes.
Chelsea, Bayern Munich, Paris Saint-Germain, Inter and Juventus will also feature, with most qualifiers being determined by a ranking system that awards points for victories in the Champions League.
