FFS you are in Porto Portugal? Are you watching the news? You can decide to work from home. First google result: https://www.jornaldenegocios.pt/economia/emprego/detalhe/tra... And second, please name the fucking company as for people to do the same and avoid it as much as possible.
It's not the legality or the right to work from home that is in question. You too live in a small country with too much corrupt politicians and networks of influence. If I named the company I would be uniquely identified by my immediate superiors as soon as they read this. I might as well ask you if you have any job for me in a couple of months. I really like Porto.
I wouldn't worry too much. For all the bad things our country has, labour court isn't one of them (well it can be) as it almost sides with workers all the time. If they try to fire you, they will end up paying you a lot and give you your contract back.
