The LAPD said Tuesday that 1,357 of its employees, most of them police officers, have failed to respond to orders to report their vaccination status to the city.

Chief Michel Moore said those officers will be served with disciplinary notices this week, NBC reports.

“We will begin that notification or notice process with each of these involved employees, that will be done personally by each of the commanding officers,” Moore said.

Discipline could include suspensions or terminations.

The 1,357 includes employees who had either responded to the city’s order to report their vaccination status who declined to share their information, and employees who failed to respond completely.

The union that represents most officers, the LA Police Protective League, said last month that it successfully negotiated non-disciplinary terminations for officers who refuse to get the Covid-19 vaccination, which would mean the officers could be rehired if they get vaccinated or the city’s requirements change.
