Heavy physical work under time pressure: the garbage collection service--a case study.

Area of Science:

• Occupational Health
• Ergonomics
• Sociology of Work

Background:

• Urbanization leads to increased garbage generation, straining waste collection services.
• Garbage collectors experience significant physical and psychosocial demands due to high workloads.

Purpose of the Study:

• To analyze the work of garbage collectors, focusing on time demands and resulting physical and psychosocial impacts.
• To identify contradictions between prescribed tasks and actual work, and the coping strategies employed by workers.

Main Methods:

• Utilized Ergonomic Work Analysis (EWA) in real-world settings.
• Included technical visits, global observations, unstructured and structured interviews, photographic, and audiovisual recordings.
• Focused on two garbage collection teams to capture task execution and worker experiences.

Main Results:

• Identified discrepancies between planned tasks and the actual work performed by collectors.
• Observed significant variability in the collection process and worker-adopted strategies to manage workload.
• Highlighted that the current system overburdens workers physically and psychosocially.

Conclusions:

• Insufficient resources and organizational management structures contribute to excessive demands on garbage collectors.
• The waste collection process is sustained by over-requesting workers, impacting their physical and mental well-being.
