fluent communication

I think formulating any HR policy is a one time activity, 
it is an on going activity where communication from both 
the sides should remains opena and once the policy 
declared, we should always remains open to make changes in 
the current policy considering the feedback we receive from 
our employees.
Because these policies are formulated for the benefit of 
the employees and their efficient working and if our 
employees are not agreed with the policies and find it 
difficult to understand/ obey.

Then what is the use of such policy.
