Hello,

Naresh

As you are new to the company .You don't know what to do then the  HR will helps you .Human resources specialists are responsible for recruiting, screening, interviewing and placing workers. They may also handle employee relations, payroll, benefits, and training.  They oversee specialists in their duties; consult with executives on strategic planning, and link a company management with its employees.  Don't worry HR helps you and explain you every thing.

GOOD LUCK!!!
