United Airlines and the union that signifies its some 13,000 pilots have reached a tentative agreement for voluntary leaves and early retirement offers, the union explained to its customers Thursday.

The probabilities for a restoration in air vacation amid the pandemic are getting much more remote with conditions of Covid-19 spiking and states like New York and New Jersey issuing travel constraints to halt the disorder from spreading, executives have warned.

The union instructed its users in a memo, which was found by CNBC, that the deal would require to be ratified by union leaders next week. The aspects weren’t quickly disclosed.

The arrangement comes a working day soon after United warned about 36,000 employees ⁠— close to 40% of its workforce ⁠— that they could be perhaps furloughed when the terms of federal aid that prohibit task cuts expire on Oct. 1. That incorporated probable furloughs of additional than 2,200 United pilots.

United is hoping to exhaust voluntary actions these as early retirements and buyouts in advance of involuntarily furloughing personnel.

American and Delta had already arrived at agreements for early retirements for pilots.
