I am from the UK and have been working for the past 5 months for a company in Barcelona. When I started working for them I was given a 3 month contract, but that expired in August - yet I have still been working for the company without them renewing my contract. In my original contract it stated that I have to give 15 days notice when leaving my employment.
My question is that I have been offered a new job with a different company here in Barcelona, but they want me to start working for them more or less immediately. As my contract has expired, am I still legally bound to give them the 15 days notice? If I don’t give my 15 days notice, what can they do to me - are they still legally bound to pay me for the recent work I have done for them? Any advice would be appreciated. Thanks.
