Access to employee data of a public service concessionary company

The City Council wants to access the workers of a concessionary company for the municipal gardening service, road cleaning and waste collection, in order to study the economic data for the purpose of assessing a possible subrogation of the service. To this end, check whether certain data of the workers are personal data and whether the city council has a legal basis to obtain this information. Data on the date of birth, professional category, type of contract and date of termination of the contract of the employees of the concessionary company referred to in the inquiry shall be considered personal data, even if provided separately of the first and last names of the working people. The city council has an authorization or legal basis to receive this information from the concessionaire given the provisions derived from both the local regime regulations and the public procurement regulations. However, the delivery must comply with the rest of the principles of the data protection regulations, in particular the principle of minimization, so it is not justified to include the first and last names of the working people affected.
