Absolutely, and I think as you get older and more experienced you become desensitised, learn how to let things go and not take your work home, because it's not a sustainable way of working.They definitely are and fixate on clients I work in social services and my younger colleagues seem obsessed with work and their cases and can get quite boring about it . They also text a lot outside of work . Especially I would say colleagues who are from quite sheltered middle class backgrounds don’t know if it’s because our area of work is so alien to them in terms of the clients and the lives they live but I can definitely relate to younger staff seeming much more fixated on work .
In relation to the dark humour, I can relate yo that, I've absolutely make jokes about similar things and it's just a way of coping.
