Maintaining Policies
Some policies are standard for all working places. For example, it's not allowed to go to the office inadequately dressed, although the dress code will differ from one company to another; unless an office party is organized, employees shouldn't be under the influence of alcohol; no type of assault is tolerated in the workplace, etc. HR managers decide what's the code of conduct based on the company culture and integrate management requests into it. Some specific instructions may be a total ban on listening to music while working or compensating for smoking breaks after working hours. Either way, HR is there to define company policies, make sure all staff is well informed about them, and notify those who break them. Sometimes, drastic measures need to be taken to reinforce the established policies.
