Following the rules and regulations of a company one works for

Q: Is there any rules and regulations about not working according to an organization's standards?

For example, I work in an organization and my job is to give bonus amount to others based on their work. There is a chart by the organization about how much bonus should be provided according to the work. But if I don't follow it and give a bonus not according to them, will it be ok or not?
