Do you Think HR professionals are not friendly with their employees? If yes Then why?

All HR professionals are to have very good relationship with their employees.

They may play a neutral role professionally between the Management and the employees.

But nothing stops tem from being friendly.

But the friend who may be an employee, needs to understand that you have boundaries which your profession demands !

Definitely NO because HR is a strategic partner of the organization as well as employees. HR would be friendly for the employees, but does not share any confidential information.

No they must be friendly. In fact how are they professionals if they  don't know how to deal with their employees . But sometimes the relationship is beyond the professionalism and can be rigorous, that employees interpret  it as  unfriendly and the employers from their side ,it is strictness particularly in companies with large number of employers , that  requirements such allowances and compensations ..etc. are unlimited

If you're not friendly, you will have a very small world in a very big office.

The job of HR officer is to achieve the objectives of the company by using the right person. 

A healthy relationship is what more required

No, HR personnels are always friendly with all other employees. Their are lot of things where HR personnel need to maintain the confidentiality of the work, while being friendly at the same time. Its not possible for HR's to satisfy all the queries of every employee every time, as need to handle & satisfy different types of attitudes of employees. some times its happen that HR personnel behave little bit unfriendly or rude, its just that they also need there work to be respected in all the ways.

A healthy relationship is the the root for an administrator.

They are always friendly and cooperative. But every person has different mood so we can not say all are good or  bad . May be they personally don't like some one then it is a different matter otherwise as a whole they want to help every one.
