Training and development help the employee to work on their weakness or let's say skills which they are lacking. It is important to expedite the acquisition of knowledge, skills, and abilities to perform the job effectively. 

It is important because it gives the employe a chance to grow in their field and perform their task more adequately.

Also, it helps the employee to achieve some promotions they are searching for.

It would not be appropriate to go to HR with personal life problems specially during office hours. However if you share a friendly relationship even outside the office with HR then you can discuss it with him/her, being your friend but not as an HR of a company.

These are some of the core functions of HR.

1.  Staffing

This includes the activities of hiring new full-time or part-time employees, hiring contractors, and terminating employee contracts

2. Development

On-boarding new employees and providing resources for continued development is a key investment for organizations, and HR is charged with maintaining a developmental approach to existing human resources.

3.    Compensation

Salary and benefits are also within the scope of human resource management. This includes identifying appropriate compensation based on role, performance, and legal requirements.

4.    Safety and Health

Achieving best practices in various industries include careful considering of safety and health concerns for employees.

5.    Employee and Labor Relations

Defending employee rights, coordinating with unions, and mediating disagreements between the organization and its human resources is also a core HR function.

6.   Development of Human Resources

Human resource development combines training and career development to improve the effectiveness of the individual, group, and organization.
