What is an Interim HR Director?
An interim HR director is a senior HR professional engaged on a temporary basis to provide immediate, full-time leadership during periods of transition, transformation, or crisis. Unlike fractional HR directors who work part-time across multiple clients, interim HR directors typically work 4-5 days per week exclusively for one organisation for a defined period — usually 3-12 months. Interim HR directors are brought in when organisations need experienced HR leadership immediately: to cover maternity leave, manage a redundancy programme, lead a cultural transformation, or bridge the gap while recruiting a permanent HR director. They bring decades of experience and can hit the ground running without the lengthy onboarding a permanent hire requires.
When Should You Hire an Interim HR Director?

Recruitment Bridge

Special Projects
You need to implement a new HRIS, redesign compensation structures, or lead a specific HR initiative requiring dedicated focus.
