Add Comment Question: How long can someone be on paid administrative leave while an ‘investigation’ is being conducted before a decision is made to terminate or keep ? Answer: There is no formal law/rule with respect to how long one can be kept on a paid leave pending an investigation, however if your leave lasts more than a few months, I would recommend you speak with a lawyer as you may have a constructive dismissal claim.
