What changes with age and what doesn’t
Work capacity is the result of a balance between an individual’s resources (health, functional capacity, skills, values, and motivation) and the demands of the job. With age, a general decline in muscle strength and aerobic capacity is observed, along with reduced tolerance for shift and night work , changes in vision (presbyopia, increased need for lighting, and sensitivity to glare) and hearing, slower recovery after intense exertion, and a higher prevalence of chronic diseases and musculoskeletal disorders. These changes are gradual, highly variable among individuals, and largely modifiable through physical activity, work organization, and preventative care throughout one’s career.
Conversely, experience, process knowledge, reliability, the ability to anticipate risky situations, and the capacity to solve complex problems increase with age. Accident statistics show that older individuals experience fewer accidents, although when they do occur, they tend to be more severe and require longer periods of absence from work. The correct preventative approach is not to treat age as a problem, but rather to manage job demands to align with each person’s capabilities at every stage of life.
Age management is conceived as a perspective that spans the entire working life: preventing damage in the early stages that manifests itself late (cumulative exposure to noise, vibrations, loads, chemical agents and psychosocial factors), designing jobs that are suitable for all ages and facilitating transitions (change of tasks, reduction of night work, return to work after illness) without discrimination.
Obligations and management criteria
- Adapting work to the individual. Article 15 of Law 31/1995 requires adapting work to the individual, which includes age, in the design of jobs, the choice of equipment and work methods.
- Particularly sensitive workers. Article 25 requires that personal characteristics or known biological condition, including age-related situations, be taken into account in the risk assessment, and that the necessary preventive and protective measures be adopted.
- Age-sensitive risk assessment. The assessment should consider the physical, sensory, cognitive, and working time demands of each position and its adaptation to the diversity of the workforce.
- Health surveillance. The assessments and protocols allow for the detection of changes in functional capacity and the proposal of adaptations or changes of position in accordance with article 22 of Law 31/1995.
- Non-discrimination. Directive 2000/78/EC and Spanish legislation prohibit age discrimination in employment; age management measures must be based on individual assessment, not stereotypes.
- Working time. Reducing night work, adapting shifts, and taking breaks are effective measures, especially for people of certain ages.
- Training and knowledge transfer. Continuous training accessible to all ages and mentoring programs preserve skills and facilitate generational renewal.
Preventive measures by area
- Ergonomic design . Reduction of loads and forced postures, mechanical aids, adjustable furniture and lightweight tools benefit the entire workforce.
- Physical environment. Improved lighting, reduced background noise, control of thermal stress and slippery surfaces.
- Organization. Task rotation, autonomy to manage the pace, recovery breaks, limits on night work and flexible hours.
- Psychosocial factors. Recognition of experience, prevention of ageism, participation in technological changes and support in transitions.
- Health promotion. Physical activity programs, prevention of chronic diseases and mental health support, on a voluntary basis.
- Return to work. Reintegration procedures after prolonged absences, with temporary or permanent adaptation of the job.
- Indicators. Age structure of the workforce, accident rate, absenteeism, limitations in aptitude and adaptations made by age group.
Organizational application: how to manage age in prevention
- Analyze the age structure of the workforce by position and its expected evolution, along with data on accidents, absenteeism, limitations of aptitude and health surveillance by age groups.
- Review the risk assessment incorporating the physical, sensory, cognitive and working time demands of each position and its adjustment to the diversity of the workforce.
- Prioritize design and organizational measures that are suitable for all ages: ergonomics, lighting, load reduction, rotation, breaks, and limits on night work.
- Establish a procedure for adaptation and job change based on individual assessment and health surveillance recommendations, without discrimination.
- Ensure continuous training accessible to all ages and organize the transfer of knowledge between generations.
- Offer voluntary health promotion programs and a return-to-work procedure after prolonged absences.
- Monitor indicators by age group, consult with workers’ representatives, and review measures periodically.
Preventive management software allows you to analyze the age structure by position, relate risk assessment to skills and adaptations, plan training, and track accident and absenteeism indicators by age group with traceability.
Limits and common mistakes
- Treating age as a risk in itself and applying generalized measures without individual assessment may constitute discrimination.
- Acting only on older people and not preventing in the early stages the cumulative exposure that causes late damage.
- Maintaining night shifts and heavy workloads without alternative adaptations for those who need them.
- Excluding older people from training and technological changes.
- Failure to coordinate health surveillance with the management of adaptations and return to work.
- Do not measure or track indicators by age groups.

Practical example
Situation: An industrial maintenance company with 320 people has an average age of 49 years in the field staff, a third of the workforce over 55 years old and an increase in long absences due to musculoskeletal disorders.
- Analysis. The prevention service cross-references the age structure with accident rates, absenteeism, and limitations of aptitude: long absences are concentrated in tasks involving handling loads and work at height , and limitations mainly affect night work.
- Measures. Mechanical aids and lighter tools are introduced, teams are reorganized to combine experience and physical ability, night shifts are limited to those who request them with a medical report, a job adaptation procedure is established, and a mentoring program is created in which veteran staff train new recruits.
- Health. A voluntary program of physical activity and prevention of chronic diseases is offered, and a procedure for returning to work with progressive adaptation is defined.
- Follow-up. After two years, long absences due to musculoskeletal disorders are reduced, adaptations are processed systematically, and the company incorporates the age perspective in all new risk assessments.
Regulatory and reference framework
- Law 31/1995, of November 8. Law on the Prevention of Occupational Risks; adaptation of work to the person (article 15), health surveillance (article 22) and protection of especially sensitive workers (article 25).
- Spanish Strategy for Safety and Health at Work 2023-2027 . Agreement of the Council of Ministers of 14 March 2023; aging of the working population as a challenge.
- Directive 2000/78/EC . General framework for equal treatment in employment and occupation; prohibition of age discrimination.
- EU-OSHA e-guide: Healthy workplaces at every age . Guidance for employers, workers and professionals on age management and safety and health.
- NTP 367. Aging and work: age management . Functional changes with age and management criteria.
Measures regarding working time, adaptation and job changes are coordinated with the Workers’ Statute and collective bargaining.
