Three of the four emergency-service workers who responded to a dying Eric Garner are back at work, while the fourth EMT remains on modified duty, officials said.

Meanwhile, The Post has learned that the Garner family’s “confidential settlement” with the Staten Island hospital that employed the two medics and two EMTs totaled $900,000.

That sum is in addition to the $5.9 million the family received from the city in July.

Two paramedics who were suspended without pay were cleared by the FDNY and reinstated “within weeks” of the July 17, 2014, chokehold death, and one EMT returned in mid-December to Richmond University Medical Center, said hospital spokesman William Smith.

The fourth responder — identified as EMT Nicole Palmeri — is currently barred by the FDNY from responding to 911 calls pending the outcome of an FDNY probe.
