A rejoiner is someone who is to be appointed as a member of a police force having previously and satisfactorily completed probation in the rank of constable prior to resigning or retiring from the service. A rejoiner must not be a member of a police force immediately before appointment. There is no automatic right to return and there must be a suitable vacancy to which a rejoiner can apply. Vacancies will have clear eligibility criteria and rejoiners will be assessed as to their suitability for the vacancy. If successfully appointed, rejoiners will be subject to a probationary period.
