This kind of behavior (promoted by HR/Legal) needs to stop. Period.
It is not about firing people by conference, phone or whatever. It is about the thanklessness and the attitude that sucks. Does it really hurt to genuinely feel and say "sorry we cannot keep you any longer. Hope you understand". No one is going to sit and whine about being laid-off but the manner of layoffs (in america at least) is getting shameful, appalling and disgusting.
However, not shocking at all. Companies have too become risk/lawsuit averse when it comes to firing/lay-offs that they all have scripted things to say because they don't want to risk a potential lawsuit. My friend was laid-off by my ex-boss (I referred him and left). I know that my ex-boss was a really nice guy who would at least apologize. During the lay-off, all my friend got was "Your position has been eliminated. Please do not use any company device and leave immediately. We will ship your stuff to you". He was even told not to talk to any co-worker while leaving. Poor guy was so heartbroken that he could not even say bye to people he worked with. You know what he was not sad about ? Finding another job.
May be I am overreacting but this is when Capitalism starts to bite. I am all in for profits, competitions, fierce business but if I ever have to layoff someone specially for no fault of theirs, you bet I will say sorry in person.It may not mean much but it is called "being human".
