Problem with working in the government

I just recently learned when I was about to tender my resignation that a government employee will not receive any separation or gratuity pay unless he/she retires. I was used to have a back-pay upon my resignation. I even received about P2k for 6 months of work in SM. The government requires private firm to give separation pay and yet they don't? A government employee has privilege of early retirement on 15 years of service. 15 years??? That's bullshit! HR or personnel department should tell this during orientation because if a person doesn't have plans to grow-old and wait for retirement benefits in the government, then working with the government is JUST A WASTE OF TIME!
