Hello Dear,

Public Sector Undertakings (PSUs) are the organizations that are completely or partially owned (51% or more share) by the Government of India. First of all you need to understand that PSU jobs are not pure government jobs and it may be possible that someday in the future they will be privatized as the government's thrust is on disinvestment these days. Working in an Indian PSUs (or any other Government organization) provides you the job security. In terms of salary they offer handsome package depending upon your job profile:

Organization                                                          Status                 Salary Structure

Steel Authority of India (SAIL)                                 Maharatna     Rs. 60,000-1,80,000

Bharat Petroleum Corporation Limited (BPCL)   Maharatna    Rs. 60,000-1,80,000

Gas Authority of India Limited (GAIL)                    Maharatna     Rs. 60,000-1,80,000

Neyveli Lignite Corporation Limited(NLC)            Navratna         Rs.20600-3%-46500

Good Luck
