Steve Cawtheray, 42, is the housing and environmental services manager at Medina BC until the end of February. Four weeks later he starts as performance review officer for the IoW Council.
Mr Cawtheray resisted an attempt by Medina BC to withdraw the redundancy notice when it heard about his new job.
Councillors have criticised the two authorities for a breakdown in communications.
Alan Greaves, Medina personnel manager, said if he had known there was a job offer on the table the redundancy offer would not have been accepted.
Max Burton, deputy personnel officer, said there was no job on the table when Mr Cawtheray was made redundant and that it had arisen afterwards.
