I found the exchange very much "outsourced". The not manager were trying to convey the message. They have no skin except delivering the message in their best manor. They likely were given a script. They didn't make the decisions and were hired to be the buffer for emotions that would naturally develop.

I'm thinking the best way is to quick rip the bandaid. "Your position has been eliminated. Your severance is four months. Your check will be direct deposited today"
