I am from Spain and I know that in Spain, for getting paid for a work you need to be employed or to be freelance (self-employed). This is the same in all other countries I know. Also in Romania, where those laws are, the Labour Code (Law 23/2003) and the Conduct of economic activities by authorized natural persons - PFA (Law 182/2016) respectivelly. Even so, I know it is possible to get paid not being contracted, neither being a PFA, in case of activities done occasionally: conferences, training, consultancy. I need to know the Law and article that supports this "third way" of getting paid.
