Hello Amruta,
i also did the project on HR Policies during my MBA internship.for this u can visit website of various companies n can study them. u wont get too much details abt it as these policies are confidential but will surely get some help. u can visit websites of companies lik amul, pepsico, maruti, reliance etc.
hr policies include company's recruitment policy, performance appraisal,leave policy, code of conduct, greivance handling, employee dress code policy, travel policy, health and safety policy etc,
moreover there are certain websites which can guide u to plan HR policies.
u can also visit certain organizations to find out what policies do these companies have for their employees, u will surely get enough data that will help u in ur project.
regards
neha
