The communication of particulars included in the mercantile contract formalized with an autonomous worker to the Works Committee has to be carried out according to the regime of article 11 LOPD. Neither the Statute of the Workers nor the Statute of the autonomous work contain general forecasts that fit out the communication of particulars included in the mercantile contract with the exception of the supposition related to the economically dependent autonomous workers. Out of this exception, with general character, it is necessary to have the consent of the person concerned in order to communicate its data.
