Ever wonder whether you’d be better off working some place else?

A new Web site called Glassdoor.com is trying to make it easier to find out by compiling free snapshots of the current salaries paid by hundreds of major employers, along with reviews anonymously written by current and past workers.

“We think it’s super important that people are able to find a job where they can go home happy at the end of the day,” said Robert Hohman, Glassdoor’s co-founder and chief executive.

The Sausalito-based startup’s other founders include Rich Barton, CEO of online home appraisal site Zillow.com.

By providing free access to sensitive salary information and sometimes blunt reviews of companies, Glassdoor is bound to upset some employers, predicted Jupiter Research analyst Barry Parr.
