Don't get me wrong, it can be (professionally) interesting to do something huge like close a site and make 500+ people's jobs redundant, but to actually have no empathy for the people going through it is, how shall we say, presenting emotional detachment.
You can sack people with dignity and respect. Doesn't take much effort, tbh.
Trouble is, a lot of HR people don't treat employees and workers with dignity and respect.
