Final answer:
Canadian studies suggest an increase in work overload that contributes to occupational stress, job strain, and potential job burnout, particularly in jobs with high demands and little control.
Step-by-step explanation:
Studies on work overload in Canada indicate several trends related to occupational stress. A heavy workload, a sense of little control over the job, and inadequate rewards contribute to job burnout. Factors such as job demands, workload, and lack of discretion in decision-making are common stressors that lead to feelings of job strain, affecting workers' mental health and satisfaction. The surveys referenced indicate rising stress levels among various demographics, including those with full-time employment, which could relate to an increase in perceptions of work overload. Certain occupations inherently have higher stress levels due to challenging work conditions and demands.
