The largest union representing the New York Police Department is planning to sue the city for “unilaterally” imposing vaccine mandates on police officers they represent.

The New York City Police Benevolent Association called out NYC Mayor Bill de Blasio for its “haphazard vaccine rollout,” standing firm that vaccination against COVID-19 should be a “personal medical decision.”

“From the beginning of the de Blasio administration’s haphazard vaccine rollout, we have fought to make the vaccine available to every member who chooses it, while also protecting their right to make that personal medical decision in consultation with their own doctor,” PBA President Patrick Lynch wrote in a statement Wednesday.
