Policies vary from organization to organization. Many clubs offer child care free of charge and many offer it to employees at a discount.
Since you adopted a “free for all” operation, you can start by analyzing trends and needs. The child care’s primary function is to serve the members. Staff needs are important, but secondary to the operation.
You can start by analyzing staff NEED for childcare and understand what is critical for them as it pertains to the success of the club.
I assume there are child care guidelines for members. Staff should adhere to these guidelines as well. For instance, length of stay requirement, reservations, employee must be in the club, etc.
The policies need to be explained to the employees, detailed in writing and strictly adhered to in order for the policy to be successful.
