    Can you really lose your job for posting an opinion on Twitter, or even for clicking "like" on someone else's message？Pascal, an employment lawyer in the Netherlands, assumes that about one in ten laying-off is connected to behavior on social media.

Controversial opinions were once expressed in bars after work, and went no further. Today Twitter and other social media broadcast employees' thoughts, making it easy for anyone offended to put together a revenge（报复）against the poster and their employer.

Though it's not necessarily in companies' interests to allow the free expression of opinion, it's clearly in society's interest. Free speech is the foundation of democracy（民主）. In laying down clear rules, we should remember that offending and harassing（骚扰）are different. It's not reasonable for companies to try to prevent their employees from expressing displeasure at something, no matter how strongly others disagree-at least if that's not relevant to the job they do. But an employee who repeatedly makes unfavorable comments at work has crossed the line into harassment, and this should be grounds for dismissal.

There's also a difference between what people do at work and what they do outside. Speech is like a dress code. Companies can demand that their employees look the part at work. After people go home, though, they should express their opinions freely, just as they're free to change into jeans and T-shirt. A woman fired in 2004 by a housing firm for displaying a sticker backing John Kerry on her car was poorly treated. The situation is more complicated when it comes to public figures such as sports stars, who in effect sell their image as well as their labor.

Firms will try to preserve their freedom, but laws against unfair dismissal that protect speech will help them stand up to complaints from angry people. Geographical and technological spaces are increasingly separated, which makes it important that people tolerate different views at work, especially outside it.
