Apply medicine according to indications
firing can not actually solve the problem, organisation should do something make the employees 'hide' their personalities.
leaders should strict their own behaviours firstly because they always be seen as an example in the organisation. leaders' behaviour will influence the employees, if the leader himself can not obey the rules or principles, how can those followers do?
the organisation should run business legally. it happens when employees know the scandal of their boss, they will become 'take over control'.
as metioned before, principles and rules are needed. During the intial training process, let the employees know what they must not do and basic principles of the organisation. if they do not agree with it, the organisation may consider whether ot employ him or not.
increase the employee satisfaction of the organisation is also important. if the employee feel happy when work in this organisation, he will be willing to stay for long time. because of this, he will make his effort and 'hide' his strong personality to adapt to the organisation. this depends on how leaders treat their employee.
leaders should develop a healty enterprise culture. empowerment is essential. when all employees have a share goal, they can make effort toward it through good cooperation. leaders should consider how to let those employee with strong personality cooperate with others. A positive enterprise culture will work better than principles.
