From Angloinfo Costa Blanca's page Working in Spain
"Work Permit
EU and EEA citizens are exempt from requirements concerning visas, passports and medical checks when entering another EU Member State. An identity card allows the holder to enter freely and to move around for three months, which is useful if you find temporary work or are seeking employment.
EU and EEA citizens do not need a work permit.
They may exercise the occupational activity of their choice. However, as soon as they have found work and no later than three months after arriving, they must apply for a "residence permit for a national of an EU Member State".
It is valid for five years and automatically renewable."
