Job evaluation in worker fitness determination.

S H Rodgers

    Occupational Medicine (Philadelphia, Pa.)
    |April 1, 1988
    PubMed
    Summary

    Accurate work fitness assessments require job-specific analysis of physical demands, not general tests. Quantitative job analysis identifies high-stress areas and informs reasonable accommodations for worker safety and legal compliance.

    Area of Science:

    • Occupational Health
    • Ergonomics
    • Workplace Safety

    Background:

    • Assessing work fitness for job placement demands specific evaluations of physical capabilities.
    • General fitness tests may not accurately reflect job-specific demands or meet legal standards like Title VII.

    Purpose of the Study:

    • To outline essential components of a quantitative job analysis for evaluating worker fitness.
    • To emphasize the importance of job-specific assessments over general fitness tests.

    Main Methods:

    • Detailed assessment of repetitive manual capabilities, static loading tolerance, and environmental conditions.
    • Quantitative job analysis to identify high-stress anatomic structures and job demands.
    • Evaluation of effort intensity, duration, frequency, and recovery times for muscle groups.

    Main Results:

    • Key factors for physical demand evaluation include effort intensity, duration, and repetition frequency.
    • Psychophysical scaling and peer ratings can estimate effort intensity.
    • Timing of effort and recovery quantifies fatigue and suggests task improvements.

    Conclusions:

    • Quantitative job analysis is crucial for identifying high-stress job components and informing reasonable accommodations.
    • Workload assessment should consider aerobic capacity, environmental factors (heat, humidity), and psychological demands.
    • Job modifications can often be implemented cost-effectively to improve worker capabilities and safety.
