If you are thinking about moving to Spain on a permanent basis then you may wish to consider employment. The best way to look for employment is in the local papers such as the Costa Blanca News or another good option is sending your CV directly to the companies you are interested in working for.
Spanish employers are generally very accepting of foreign workers and the contract laws are very strict so workers are heavily protected from exploitation. Ensure that you receive an official work contract from your employer and read or translate it carefully. Temporary contracts are for 3, 6 or 9 months and after this employers are obliged to offer a permanent contract.
