It is about doing unpaid work. Most progarmmers - at least in the us - are not paid by the hour and so you get nothing for you extra time put in which is not ethical for them to ask. It is perfectly leagal for you to do it.
laws and ethics are often different but many fail to realize that.
If someone does unpaid work on weekends and it is not done as hobby or something they are very silly, exploited or both.
> which is not ethical for them to ask
definitely, though I am highly confused why someone would agree to this (unless they are basically enslaved or something which would make it even blatantly unethical)
I guess that if you agree to sky-high wages with implicit agreement to work absurdly long hours, despite written contract being different?
> laws and ethics are often different but many fail to realize that.
not sure about "many", people in general I quite happy to break laws, especially ones widely agreed to be silly and not enforced at all
