Read the following scenario and answer questions.
Organizations have a long history of managing returns to work involving cases of physical disability. However, evidence from WCBs across Canada shows that claims involving disability due to mental health issues are the fastest growing segment of disability claims. Heavier workloads from flatter organizations and hiring freezes have put increased pressure on workers in many industries. Information and communication technologies have greatly increased the pace of work and blurred the boundaries between work time and non-work time (family time, leisure time, or community time) . Mental health absences from work can also be as a result of being involved in or seeing a traumatic incident in the workplace.
