They are humans, of course they like and dislike doing things. However, that doesn't define work. You can also dislike your work. Still, you are paid for it.
When I'm done for the day I don't want to sit in front of a computer any longer. I can understand why a cook would come home and just throw down a microwave meal. The issue here isn't getting paid, it's doing the same when you get home. My current employer won't renew my contract because I oppose this mentality, it's toxic and making me debate leaving IT altogether. He considers me lazy for that. Is some balance really too much to ask?
> My current employer won't renew my contract because I oppose this mentality
That's crazy. Everyone should be free to do whatever they want in their own free time.
>it's doing the same when you get home
That's what my colleague answered me when I asked him "why don't you have side projects?". Everyone should be able to choose whatever they want to do with their own free time.
I don't consider a side project as "the same thing I do at work", and I don't consider myself special.
