The reality is the layoff decision has been made. There is no undo. It is better to cut cleanly as it allows people to move on faster than drawing it out.
The best thing for the most people is to help them move on to the next gig quickly.
The people u work with bosses included, are what make or break this. In my experience, people help one another. I have seen ceo’s push resumes of people let go to other execs in their network. This is outside company policy or communication for legal reasons but not everyone is dirt bag.
If you mean clean cut as in only cleanly cut the contract, but then maintain the relationship in other ways, I think that could make sense, as it doesn't pretend the decision hasn't already been made. I think I was reacting to clean cut the relationship completely, which I don't even think works well. But yeah, I'd appreciate if the individuals or even the company helped the people out.
It'd be like ending a relationship with someone who was financially dependent on you and just letting them fall of the cliff, compared to saying that you know it doesn't work for you two together, but you'll financially help them transition. I dunno, some people should say clean cut the relationship, drop friendships, never talk, cold turkey, I just don't know how well that works for human well being in the long term.
