There is no prescribed size of company that the protection policy works best for. The monthly retainer price is calculated to be based on the wage roll and history of Employment Tribunal claims of the company. This includes a legal advice fee and also the insurance premium. So, for a smaller company, employing only a few people, the monthly retainer would likely be cheaper than a larger company, with more staff. However, the policy is designed to protect large and small companies, at a price which is applicable to their specific circumstances.
