Return to Work interviews just for sickness? We advise return to work interviews for all instances of absence and lateness which are not authorised prior to them taking place. Having a consistent approach gives you the best opportunity to investigate and decide appropriate courses of action. In some cases, there are underlying issues for absence and lateness and additional support to your employee may be required. A consistent approach also acts as a deterrent to those who do not have genuine reasons for their absence or lateness.
