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.
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.
