The specifics aren't yet known, they only approved the generality of the law. But the news only mentions employers, so it doesn't seem like it will include co-workers. Also your example would be considered an infraction.

Another reason why it won't mean much is that the employee is the one that needs to make a complain with the work authority, and then work authority has to evaluate the case and decide it they will issue a fine or not.

So what this really means is that if my boss contacts me after work hours I can (and should) ignore him without any repercussions.

Ahhh thank you this makes a lot more sense - the law doesn't need to define "contact" very closely, if there is a review board that decides whether to fine, rather than an automatic fine.
