All of the listed options can be helpful in becoming familiar with your company's policies and procedures. However, the most comprehensive and reliable source would likely be to look in the employee handbook. This resource is typically designed to provide employees with information about the company's policies, procedures, and various other guidelines. If you are unable to find the information you need in the handbook, you can reach out to the person who hired you or your supervisor for additional assistance. Additionally, visiting the company's website may also provide valuable information and resources related to policies and procedures.
