How much do your peers make?

Ever wonder whether you’d be better off working someplace else? A new website, Glassdoor.com, is trying to make it easier to find out by compiling free snapshots of the salaries paid by hundreds of major employers, along with anonymous company reviews written by current and past workers.

By providing sensitive salary information and sometimes blunt reviews of companies, Glassdoor is bound to upset some employers, Jupiter Research analyst Barry Parr predicted. “It just makes me wonder how long it will take before they get sued.”

Glassdoor is allowing visitors to look at the salary information and reviews of four high-tech heavyweights -- Microsoft Corp., Google Inc., Yahoo Inc. and Cisco Systems Inc. But to get the skinny on other companies, visitors must reveal their salaries and feelings about their employers.
