NFL teams have had a history of putting their logos on jerseys and apparel for years, but now it appears that it’s getting a little bit harder for teams to get away with that.

    According to ESPN, the NFLPA has filed a grievance over a rule that would allow teams to put their logo on jerseys or apparel without a union, and the NFL says it will fight to overturn the ruling.

    The grievance, filed Friday in the National Labor Relations Board, is a way for NFL teams to show that they’re being treated unfairly by the union, NFLPA President DeMaurice Smith said in a statement.

    The grievance has already forced teams to back down on a number of past requests to put the logos on their uniforms.

    According the league, the logo rule would allow for teams that don’t have an NFL franchise to put a logo on their jerseys or uniforms without the union’s consent, without requiring a union vote.

    In a statement, the league said it will defend the rule against the grievance.

    Smith, in her statement, said the league’s rule is an attempt to take away bargaining power from unions.

    The league is asking the NLRB to hear the grievance in court, so that it can be decided.

    The NFL has a long history of using its franchises to put logos on uniforms and apparel.

    In 2010, the Atlanta Falcons, who had been an independent franchise since 1984, signed a five-year, $12.9 million deal with the league to have their logo in every uniform and apparel from the 2013 season.

    That same year, the Indianapolis Colts, who were also an independent, had their logo featured on their helmets.

    The NFL also released the logo to the Detroit Lions in 2014.

    The AFL-CIO, which represents the NFL, has argued that the NFL has no legal authority to put its logos on its uniforms and jerseys.
