Be aware of their physical condition. For example, a worker who is out of shape is more susceptible to back injuries. A worker returning to work after recovering from a job injury might not be physically up to performing his or her regular job for a while. Or an employee with a physical disability might need accommodation to safely perform a job.
Also, be on the ookout for problems like fatigue or illness. Either one can affect performance and place the employee or someone else at risk. Overtired workers or people nursing a cold or the flu aren’t going to be at their best, and that could be dangerous, especially if they’re performing a hazardous job.
Change an employee’s job duties temporarily-or even permanently, when necessary-if he or she is incapable of performing a job safely.
