Automatic summary, not yet reviewed
- Employers who have workers without Social Security registration can register them voluntarily until July 31, 2011. If they do, they face no administrative fines for those situations and can defer their Social Security debts under certain conditions.
- Employers who join the regularization process must sign an employment contract with the worker, under any type of contract. Temporary or fixed-term contracts must have an initial duration of at least six months, and the contract must state that it falls under this process.
- Once the regularization period ends, companies that contract or subcontract work or services related to their own activity, or provided on a continuing basis at their workplaces, must check before the work starts that the contractor's or subcontractor's workers are registered with Social Security. Failing to make this check becomes a serious offense.
- Fines increase for failing to register workers and for obstructing labor inspections in this area: serious offenses can reach €10,000 and very serious offenses €187,515. Companies fined for these behaviors can be excluded from employment program benefits for up to two years, and those sanctioned with the serious offense in Article 22.2 are banned from contracting with public administrations.
- If an employer joins the regularization without meeting the requirements, or fires the worker before six months, it loses the benefits of the process, must return any aid received and pay the Social Security contributions. The Government will evaluate the results of the law after six months, after hearing the Tripartite Advisory Commission of the Labor and Social Security Inspectorate.
