We have an employee who recently underwent disciplinary action, was issued with a final written warning and subsequently went on sick leave.

The employee in question followed the correct self-certification procedure but has not been heard from since (almost a week now). He has in the past refused to give personal contact details (we have an old address on file and no contact number) so we cannot get hold of him to find out where he is. We have tried to contact him on his work number and left sveral messages, however he has not responded.

I understand we have to wait a couple of days for a sick note to come through, but legally we are not sure where we stand on this as our HR was previously outsourced.

Also, does this employee have a legal obligation to offer correct contact details?

Thanks for any help.
