    Occupational contingencies (Spain)

    Occupational contingencies are situations covered by the Social Security system that originate in the workplace: work-related accidents and occupational diseases. These are distinct from common contingencies (common illness and non-work-related accidents), and this distinction determines who manages the benefit, what contribution requirements apply, what amount is received, and what notification and investigation obligations fall on the employer. In Spain, the consolidated text of the General Social Security Law, approved by Royal Legislative Decree 8/2015, defines a work-related accident in Article 156 as any bodily injury suffered by a worker on the occasion of or as a consequence of work performed for another party, with a presumption of work-relatedness for injuries suffered during working hours and at the workplace. It defines an occupational disease in Article 157 as one contracted as a consequence of work in the activities and by the agents listed in the table approved by Royal Decree 1299/2006. Coverage for these contingencies is the responsibility of the managing entity or the mutual insurance company collaborating with the Social Security system chosen by the company, and notification is carried out through the Delt@ (accidents) and CEPROSS (occupational diseases) systems. For prevention, the registration and analysis of occupational contingencies are the main source of data on accident rates and the effectiveness of preventive measures.

    In short

    Situations covered by Social Security that originate in the workplace include work-related accidents (Article 156 of the General Social Security Law) and occupational diseases (Article 157 and the table in Royal Decree 1299/2006), as opposed to common contingencies. The classification determines the managing entity (mutual insurance company or managing entity), the absence of a waiting period, the amount of benefits, any applicable surcharges for lack of safety measures, and the reporting (Delt@ and CEPROSS) and investigation obligations. Their registration and analysis form the basis of accident statistics and the monitoring of preventive effectiveness.

    Work accident and occupational disease

    In addition to injuries sustained at the workplace, a work-related accident includes the situations covered by Article 156 of the General Social Security Law: accidents occurring while commuting to or from work; accidents sustained while performing elected union duties; accidents occurring while performing tasks outside the scope of the employee’s professional category, carried out on the employer’s orders or in the interest of the company’s proper functioning; accidents occurring during work-related rescue operations; illnesses not included in the list of occupational diseases when it is proven that they were caused exclusively by the performance of work; and pre-existing illnesses or conditions that are aggravated as a result of the injury constituting the accident. Accidents due to force majeure unrelated to work and those caused by the employee’s willful misconduct or reckless imprudence are excluded, while professional negligence and the involvement of a third party do not preclude classification.

    Occupational disease requires that the pathology and the activity or causative agent be listed in the table of Royal Decree 1299/2006, organized into six groups: chemical agents, physical agents, biological agents, inhalation of substances, skin diseases, and carcinogens. The system is based on a list, with a presumption of work-related origin when the elements of the table are present, which facilitates recognition. Work-related illnesses not on the list may be classified as work-related accidents if an exclusive causal link is proven.

    Occupational contingencies also include periods of observation for occupational illness and situations of risk during pregnancy and breastfeeding, which the law treats as work-related contingencies for the purposes of benefits. Self-employed workers may have coverage for occupational contingencies under their own specific policies.

    Effects of the qualification as a occupational contingency

    • No waiting period. Benefits for work-related contingencies do not require a minimum prior contribution, unlike temporary incapacity due to common illness.
    • Benefits from the following day. Temporary disability due to occupational contingencies is paid from the day after the leave begins, with a regulatory base that includes overtime and a higher amount than that for common contingencies.
    • Healthcare and rehabilitation. The mutual insurance company or managing entity provides healthcare, rehabilitation and, where applicable, vocational retraining.
    • Benefits for permanent disability and death. The amounts and lump-sum compensation have specific and more favorable rules when they arise from occupational contingencies.
    • Surcharge on benefits. If the contingency occurs due to a lack of safety and health measures, Article 164 of the General Social Security Law provides for a surcharge of between 30 and 50 percent of the benefits, to be borne exclusively by the employer and not insurable.
    • Responsibilities. The rating may entail administrative, civil and criminal liability for the employer when there is non-compliance with the preventive regulations.
    • Contribution. The contribution for occupational contingencies is made according to the premium rate for economic activity (CNAE) included in the General State Budget Law, at the sole expense of the company.

    Notification, registration and management

    • Work accident report. Order TAS/2926/2002 establishes the models for accident reports with sick leave, lists of accidents without sick leave and lists of discharges or deaths, and their electronic transmission through the Delt@ system; in accordance with the Order of December 16, 1987, the report with sick leave is submitted within a maximum period of five working days, counted from the date of the accident or from the date of sick leave (article 3.a), and serious, very serious, fatal accidents or those affecting more than four workers are reported to the labor authority within twenty-four hours (article 6).
    • Occupational disease report. Order TAS/1/2007 establishes the model for the occupational disease report, completed by the mutual insurance company or the managing entity with the collaboration of the company, through the CEPROSS system.
    • Mutual insurance companies. Royal Decree 1993/1995 regulates the collaboration of mutual insurance companies in the management of occupational contingencies, including healthcare, financial benefits and preventive activities.
    • Investigation. Article 16.3 of Law 31/1995 obliges the employer to investigate damages to health when they occur, regardless of the classification by Social Security.
    • Record keeping and documentation. The list of accidents and occupational diseases resulting in absence of more than one day is part of the documentation that the company must keep and make available to the labor authority.
    • Determination of the contingency. When there is a discrepancy regarding the common or occupational origin, the National Social Security Institute resolves the contingency determination procedure, with possible judicial review.

    Organizational application: how to manage occupational contingencies

    1. Define the internal procedure for communicating accidents and incidents, including responsible parties, deadlines, and notification channel to the mutual insurance company or managing entity.
    2. Issue the accident report with sick leave in Delt@ within five working days and report serious, very serious, fatal or multiple accidents within twenty-four hours; submit monthly the list of accidents without sick leave.
    3. Collaborate with the mutual insurance company in completing the occupational disease report and in monitoring the observation periods.
    4. Investigate each health injury in accordance with Article 16.3 of Law 31/1995, identify causes and adopt corrective measures, regardless of the classification of the contingency.
    5. Register and keep documentation of accidents and occupational diseases and keep accident rates up to date.
    6. Review risk assessment and preventive planning based on contingency data, and analyze the relationship with absenteeism and health surveillance.
    7. Inform the worker safety representatives and the health and safety committee of the damage caused and the measures taken.

    Preventive management software allows you to record accidents and incidents, generate the necessary data for reports, manage the investigation and corrective measures, calculate accident rates and relate contingencies to risk assessment and health surveillance with traceability.

    Limits and common mistakes

    1. Confusing the classification of the contingency by Social Security with the preventive obligation to investigate: the latter exists whenever damage occurs.
    2. Failure to report accidents resulting in sick leave or serious accidents within the established timeframe constitutes an administrative offense.
    3. Classifying work-related illnesses as common contingencies, depriving the person of the benefits to which they are entitled.
    4. Ignoring occupational diseases due to a lack of diagnostic suspicion and coordination with health surveillance.
    5. Not analyzing contingency data to review risk assessment and planning.
    6. Ignorance of the surcharge on benefits and the responsibilities arising from the lack of safety measures.

    The specific requirements for benefits, contributions and notification are detailed in the General Social Security Law and its implementing regulations; this sheet is for informational purposes only.

    Practical example

    Situation: A logistics company worker suffers a back injury while handling a load and is on medical leave; months later, another worker from the same warehouse is diagnosed with shoulder tendinopathy.

    • First case. The company reports the accident to the mutual insurance company, submits the accident report with sick leave to Delt@ within five working days and the prevention service investigates the event: a load above what was assessed and absence of mechanical aids are identified, and corrective measures are adopted.
    • Second case. Health surveillance detects the relationship between the pathology and the repetitive movements of the job; the mutual insurance company completes the occupational disease report in CEPROSS as it is a pathology included in the table of Royal Decree 1299/2006 for the tasks performed.
    • Effects. Both situations are processed as occupational contingencies, without a minimum contribution period and with the corresponding benefit; the company reviews the ergonomic assessment of the warehouse and the preventive planning.
    • Follow-up. Both cases are incorporated into the accident rates, reported to the health and safety committee, and used to prioritize the acquisition of mechanical aids and training in load handling.

    Regulatory and reference framework

    The premium rate for occupational contingencies is set out in the General State Budget Law and the determination of contingency is processed before the National Institute of Social Security.
