ALBANY, N.Y. (AP) — New York fired more than 2,000 prison guards Monday for failing to return to work after a weekslong wildcat strike that crippled the state's correctional system, but said enough officers had come back on the job to declare the illegal work stoppage over.

“After 22 days of an illegal strike, the governor and I are happy to report it is now ended,” Commissioner Daniel Martuscello said during a virtual press briefing.

He said the National Guard would remain in place at prisons in a support position while the department undertakes an aggressive recruiting campaign to attract additional employees. About 10,000 security staff are available to work in prisons across the state, he said, down from about 13,500 before the wildcat strike.

“Termination letters have been sent to over 2,000 officers who remained on strike. Officers and sergeants who did not have preapproved medical leave and didn’t return by this morning, 6:45 a.m. deadline, have been terminated effective immediately,” Martuscello said.
