Ever had a bad job before? When you were done working there, did you have the urge to steer others clear of treading the same path of personal destruction? I know I did. At one of my old jobs, people were so angry after layoffs that they started their own anticompany blogs.
For the slightly more level-headed there's JobDud, a site that lets you anonymously rant about how good, or bad an employer is. Like Yelp, JobDud uses a five-star rating and each company gets its own page where user reviews are listed and put together for an aggregate score. JobDud covers 21 major cities including Los Angeles, New York, and San Francisco, which seem to be the most active so far.
So what's in it for you to post to the service? For most, it's merely a chance to get something off your chest, and if it's a good place to work you can let others know about it. The site's creators hope JobDud can serve two major purposes: help people on their job hunts by sorting out the good from the bad places to work, and give companies a quick gut check on what their employees think.
The service has been live for three months, and to be honest, there aren't a whole lot of listings, so you're unlikely to see information about that job you just found on Craigslist. However, I really like the idea and the execution. Despite the fact that job satisfaction is subjective, and any number of things frequently change at any company, everyone deserves a heads up on a potential employer--be it good or bad.
