The State Police Association of Massachusetts (SPAM) said dozens of troopers have submitted their resignation papers as a result of the state’s COVID vaccine mandate.

The state is requiring all executive department employees to show proof of vaccination by October 17, or risk losing their jobs, WBZ reports.

About 20% of State Police employees are not vaccinated, the union’s attorney said.

Last week, a judge denied a request from the State Police union to put a hold on Baker’s vaccine mandate for troopers.
