What happens , when i don't follow rules of an organization ?

Simply you have to be transfered to internal invistigation and then after that you should penelty according to the company internal policies

There are formal and optional rules.Having formal work rules in work even if they're not required, is a good idea because they can help to protect business from litigation and maintain a high quality of work life for employees and employers. Employees should understand what is expected from them, not only in the work that they do, but in their behavior and in other areas of their employment relationship. If the rules are carefully selected, clearly related to the business, and fairly enforced, they can help to better management of  workplace and workers.
