I am sorry to say, but if you want to create a policy as you mentioned, yet you are expecting to receive a policy from another person, it is better to first understand your whole organization's situation. This includes aspects such as company culture, past history, nature of the employer, manufacturing processes, and more. Without knowing all these things, how can anybody provide or create a policy for your company?
Steps to Create a Policy
It is advisable to take the time to assess your organization's situation, engage in discussions with senior management, study labor law rules, and then refer to policies from companies similar to yours. Avoid simply copying and pasting policies. Instead, conduct your research in your unique way. This process may take some time, but eventually, you will be able to establish your own policy.
