Thousands of unvaccinated Big Apple city workers are set to lose their jobs Friday, which marks the end of the grace period to get a COVID-19 jab.

Nearly 4,000 of the city’s roughly 400,000 municipal employees are at risk of getting axed under the divisive mandate made by the previous administration in October, the city has said.

Current Mayor Eric Adams confirmed this week that he will go ahead with the terminations despite legal objections and a swell of protests, including a march to City Hall.

FDNY paramedic Carin Rosado was among those protesting Friday. The 33-year-old frontline worker told The Post she will likely have to leave the Big Apple after getting cut from her job of 10 years.    

“I’m about to lose my apartment, my car … I can’t afford to live in New York City without a job,” she said.

But it was worth it to fight “for my freedom,” she insisted. 

“We start here, where is going to end? It’s the first shot, the second shot, they are moving to boosters, they want to implement other shots — I’m not going to let it go that far. I’m stopping it right here.”

Rosado said she will likely move to “somewhere where they respect your freedom.”

“New York is so stubborn to stay on course and continue to implement controls, and that’s not for me,” she said.

Still, “100%, it’s in my heart that this is the right thing to do,” she insisted.

Meanwhile, Mayor Adams has insisted that the city is “not firing” anyone.

“People are quitting,” he said at a news conference Thursday.

“The responsibility is clear. We said it: If you’re hired, if you get this job, you have to be vaccinated. If you are not following the rules, you are making that decision,” he insisted.

“I want them to stay, I want them to be employees of the city, but they have to follow the rules,” he said.

The mayor has repeatedly stressed that he wants to keep all the employees, singling out police officers, firefighters and teachers, the groups widely hailed as heroes throughout the pandemic.

The latest figures show that around 95 percent of the city’s workforce has received at least one dose of the vaccine, up from 84 percent when the mandate was announced by previous Mayor Bill de Blasio.

Those expected to be let go Friday include the roughly 3,000 who have been without pay since failing to meet a November vaccination deadline, as well as some 1,000 city workers hired since the rule went into effect who have not shown proof of vaccination, City Hall has said.

However, Adams stressed Thursday that the exact number was not clear because the system had yet to update those who decided at the last minute to get jabbed rather than canned.

Adams has repeatedly stressed that he wants to keep all the employees, singling out police officers, firefighters and teachers, the groups widely hailed as heroes throughout the pandemic.

But he said maintaining “a clear direction” was more important to ensure ongoing safety before “the next strain comes out.”

“We have to be very clear. People must be vaccinated if they are New York City employees,” he said.

“Everyone understood that, and we have to follow that.”

At the same press conference, Adams said he wanted to “get rid of these darn masks so bad” — but would “err on the side of caution” before lifting all the ongoing restrictions.

“Here’s my biggest fear: We prematurely get excited and say, ‘Let’s just throw caution to the wind.’ I don’t want the city to shut down again,” he said. 

“The discomfort of wearing a mask for a short period longer … I’d rather live with that than prematurely say, ‘Let’s just get rid of them’ and end up right back where we started from,” he said.

The latest figures show that around 95 percent of the city’s workforce have received at least one dose of the vaccine, up from 84 percent when the mandate was announced by then-Mayor Bill de Blasio.
