Hi

It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that
Article 6 of decree 842/2015 regarding transferring workers from one employer to another

The employee can transfer his residency from his employer after three years service (Since the date of issue of his work permit) without the approval of the employer
Still he's obliged to give his employer the legal notice period according to article 44 of law No 6/2010

In the event that the intended question is otherwise, you can kindly ask us in detail and we will respond to it in the shortest time frame.
