Nerval's Lobster writes: So what if you work for a tech company that offers free lunch, in-house gym, and dry cleaning? A new survey suggests that a majority of software engineers, developers, and sysadmins are miserable. Granted, the survey in question only involved 5,000 respondents, so it shouldn't be viewed as comprehensive (it was also conducted by a company that deals in employee engagement), but it's nonetheless insightful into the reasons why a lot of tech pros apparently dislike their jobs. Apparently perks don't matter quite so much if your employees have no sense of mission, don't have a clear sense of how they can get promoted, and don't interact with their co-workers very well. While that should be glaringly obvious, a lot of companies are still fixated on the idea that minor perks will apparently translate into huge morale boosts; but free smoothies in the cafeteria only goes so far.
