BACKGROUND: Beyond workload and specific environmental factors, flight attendants can be exposed to irregular working hours, conflicting with their circadian rhythms and having a negative impact in sleep, fatigue, health, social and family life, and

The growing production of waste and increased use of water and sanitation systems worldwide have been pressuring the water, sanitation, and waste sectors. This study analyzed the perception of the determinants of work activity among workers from the water, sanitation, and waste sector in Portugal, the variation in the work demands among different shift types, and the main predictors of sleep disturbances. Data collection was performed through a questionnaire administered to 300 workers in 2017 and 2019. An ageing population was identified in all shift types. Possible occupational trajectories with changes from the fixed night and early morning shifts to daytime and fast rotating shifts may be linked to health conditions. Workers in fixed night and early morning shifts perceived higher physical demands and environmental discomfort, lower social support, and job dissatisfaction. Workers in daytime or fast rotating shifts perceived higher cognitive demands. Sleep disturbances were perceived more negatively among those working permanently on night and early morning shifts. The main predictors of sleep disturbance in both years were the type of shift, and high physical demands. The study highlights the relevance of characterizing the work demands to establish future strategies to improve the health and well-being of shift workers.
