It is important to have a company handbook that all new hires have access to and sign off that they acknowledge and understand.
This handbook should outline your company policies, including but not limited to:
Shift Meal Policy
Shift Notification Policy (what is considered acceptable notice, late..etc)
Payroll frequency
Break policy
Uniform Policy
This handbook is only to be used as an example. We recommend creating a handbook with the help of your attorney - policies may vary according to local laws and regulations.
These individual policy sheets should be used as templates for your own policies, relavant for your own city/state laws. It's always a good idea to ensure new hires understand and sign off on important policies.
