Como dizer "Programa de demissão voluntária" em inglês

On the employer side it could also be called "voluntary resignation incentive program incentive". Another way it´s called is "voluntary separation (incentive) ". Which are usually "voluntary redundancy programmes".

And there is the "voluntary early retirement incentive program" too, a slightly different one.
I appreciate that you worded your question in English. I have noticed that, congrats!
