The CEA is a large company, and therefore is required by law to provide its employees with various benefits. They are dealt with by societies (“associations”, in French) divided per type of action. All of them are listed on this page:

The societies include:

• Sports clubs: many sports are represented. For some, classes are offered, for others, matches or trips are organised. In some cases members can have reduced rates for entering sport facilities close to the laboratory. http://www-saclay.cea.fr/ascea/
• Holidays: you can obtain reimbursement of part of your holiday expenses.
• Theatre and opera: Cheaper theatre and opera tickets are available for some of the best venues in Paris.
