Once a business has reached a certain size, you will probably have a competent in-house HR department with fully utilised HR professionals. You need to keep your business on-track and not miss anything important; however, you will often have a short term additional piece of work or project with a need for a highly qualified professional input. This may be to cover assistance with due diligence for a proposed merger or acquisition, redundancies, organisational development, TUPE or you may require support with complex and discreet projects.
Additionally you may be supporting the movement towards having more women on boards and might wish to provide your senior female talent or upcoming stars with an external coach or mentor.
