Agree it is a shitty thing to happen and companies should avoid it where possible.
However I will give some advice to those who haven't experienced it yet..
You can either be sad and angry about it and be negative all day, or you can look at the flip side and tell yourself there is something better out there for you.
When I lost my job many years ago, I was sad that I would not get to work with the people that I got used to working with and even some of them were mates from UNI. However at that point in my life I said you know what, fuck it, let me see beyond my bubble and see what is out there based on the years of various experiences that I gained.
In turn by telling my sell you deserve something good in your life and not caring about my small little bubble I ended up finding a great job were I normally wouldn't even consider applying. Moved to a new state and been at the same company now for 10 years. Have made many great new friends and work colleagues are all nice and supportive of each other.
There are also plenty of personal live experiences I would not have gained if I stayed in my safe small bubble. I would not change it for the world. Loosing that job was the best thing for my life as it created a better opportunity. However I wanted to look for that opportunity, it does not just land on your lap.
