A ‘phased return to work’ includes returning to work on reduced hours, lighter duties or different duties.
For instance, if someone’s been on sick leave due to an accident that affected their physical health, and part of their job requires heavy lifting; that element of their job would be omitted from their duties.
Of course, you and your employee should agree on a plan for how long the phased return will last. For example, you might agree to review how things are going after a month and then decide to increase the working hours or duties, or you might decide to continue with the changes for a little longer.
Note that you should continue to review the employee’s health and wellbeing in the workplace and make new adjustments if necessary.
