Medical fitness for work

Legal framework: health surveillance, voluntariness and confidentiality

Article 22 of Law 31/1995 obliges employers to guarantee workers periodic health surveillance based on the risks inherent to their work. Participation is voluntary for the worker, except in three cases: when it is essential to assess the effects of working conditions on health; when the worker’s health condition could pose a danger to themselves, others, or other persons related to the company; or when a legal provision establishes it for specific risks and particularly hazardous activities. Surveillance is carried out by healthcare personnel with accredited technical competence, training, and capacity, and the results are communicated to the worker. The employer and those with preventive responsibilities are only informed of the conclusions regarding the worker’s fitness for the job and the need to introduce or improve protective measures.

Article 37 of Royal Decree 39/1997 details the healthcare functions of the occupational health service: initial health assessment upon joining the workforce or being assigned new tasks with new risks, assessment after prolonged absences due to health reasons, and periodic monitoring, including occupational health history, examination, and tests in accordance with the protocols approved by the Ministry of Health and the autonomous communities. Law 41/2002 on patient autonomy and data protection regulations govern consent, information, and the safekeeping of clinical documentation, which may only be accessed by healthcare personnel and health authorities.

The fitness assessment must be based on knowledge of the risks and demands of the job, not on generic criteria; therefore, the occupational health and safety service needs a risk assessment and a job description to design monitoring and issue a well-founded conclusion. Guidelines from the Ministry of Health and scientific societies specializing in occupational medicine provide criteria for assessing fitness and limitations.

Types of ratings and consequences

• Suitable. The person can perform the job duties without restrictions, with the preventive measures provided for in the assessment.
• Suitable with limitations or restrictions. Can perform the job provided that adaptations are adopted (limitation of certain tasks, exposures or times, additional measures) that the employer must implement in accordance with article 25 of Law 31/1995.
• Temporary unfit. Transitory situation, for example during a recovery process or temporary incompatible exposure (pregnancy, treatment), which requires reassessment within a defined period and, in the meantime, adaptation or change of position.
• Unfit. The person cannot perform the essential tasks of the position without risk to their health or that of others; this opens the way for a change to a compatible position where one exists and, failing that, the applicable labor and Social Security procedures.
• Pending assessment. When the assessment could not be completed or additional evidence or reports are required; it is not a final rating.
• Workers particularly sensitive to occupational risks. The suitability incorporates the protection of people with personal characteristics, biological condition or disability that make them especially sensitive, and of pregnant workers, those who have recently given birth or are breastfeeding, in accordance with articles 25 and 26 of Law 31/1995.
• Communication. The worker receives the complete results; the employer receives only the fitness conclusion and preventive recommendations, in writing and with a record.

Fitness for work and related legal concepts

• Temporary and permanent disability. Medical fitness for work is different from Social Security disability: a person with permanent disability for their profession may be fit for another position, and a rating of unfit does not equate to disability.
• Mandatory sectoral assessments. Certain activities require assessments with content and frequency set by specific regulations ( ionising radiation , asbestos , carcinogens, noise, mining work, diving, crews, professional drivers with traffic regulations).
• Pre-employment medical examinations. Health surveillance relates to the job and cannot be used as a means of personnel selection or as a condition for hiring, regardless of risks, with respect for non-discrimination.
• Job adaptation. A restricted job rating requires adapting the job or assigning a compatible one; failure to adapt is an infraction and may result in liability.
• Return to work after prolonged absences. The health examination following a prolonged leave allows for the detection of the work-related origin of the injury, assessment of fitness for work, and recommendations for adaptations for the return to work.
• Collective surveillance. The aggregated and anonymized results allow for analysis of the relationship between risks and health in the company and for review of the assessment and measures.

Organizational application: how to manage medical fitness for work

1. Provide the prevention service with the risk assessment and the description of tasks and requirements of each position in order to design health surveillance and substantiate fitness.
2. Identify the positions with mandatory surveillance due to specific regulations or risk to third parties and those that are voluntary, and inform workers of their rights.
3. Plan initial, periodic and long-absence health examinations, with the frequency of applicable protocols.
4. Establish the communication circuit of the fitness conclusions to the employer and the preventive managers, guaranteeing the confidentiality of the clinical data.
5. Define the procedure for action in the event of restricted or unfit qualifications: analysis of adaptations, change of position, participation of the prevention service and of the workers’ representatives, and deadlines.
6. Integrate the protection of particularly vulnerable workers and maternity into risk assessment and fitness management.
7. Record the qualifications and adaptations adopted, with restricted access, and review positions with recurring restrictions as a sign of preventive improvement.

Preventive management software allows planning of assessments by position and frequency, recording fitness conclusions with separate access control from clinical information, managing restrictions and adaptations with responsible parties and deadlines, and alerting of expirations and re-evaluations.

Limits and common mistakes

1. Receiving or requesting clinical data from workers instead of a fitness conclusion.
2. Using health surveillance as a criterion for personnel selection or making hiring conditional on the risks of the position.
3. Issuing generic ratings without knowing the real risks and demands of the position.
4. Do not adapt the position or assign another compatible one after a restricted rating.
5. Imposing recognitions in positions where surveillance is voluntary, or not carrying them out where it is mandatory.
6. Confusing fitness-for-work assessment with Social Security incapacity or with performance evaluation.
