Boston city employees are encouraged to speak their minds and share any thoughts they might have on the city’s bid for the 2024 Olympics — as long as said thoughts are favorable to the effort to host the games.

City employees are formally banned from criticizing Boston’s bid for the 2024 Summer Games after mayor Marty Walsh signed an agreement with the United States Olympic Committee, The Boston Globe reported Wednesday, citing documents obtained through a public records request. The joinder agreement stipulates city employees must promote the bid “in a positive manner,” according to the Globe.

It’s not clear what repercussions employees would face for running afoul of the ban.

Even with public employees silenced, Boston’s bid has run into plenty of criticism since the city was chosen as the U.S. candidate for the games. Mass protests are reportedly planned to thwart the bid and Walsh has had to deflect concerns that building the infrastructure for the games will not be another “Big Dig situation.”
