Your severance package is dependent on your training your replacement. We're talking months worth of pay which is nothing to sneeze at since you have nothing to gain from walking away from that severance.
Another way to think about this is that, depending upon how long of a notice they give, that severance could be equivalent to double or triple pay to train a replacement.
If you're going to leave anyways, then what incentive is there to say no to getting that double or triple pay
I'm guessing that's not a realistic option for people in jobs where automation is taking place. The companies that would otherwise hire them are probably automating or planning to automate.
If they have the resources, then retraining themselves for another job might be worthwhile, but just leaving their current job probably won't help them much.
