It is extremely accessible and most employers check it and do their due diligence on you just by seeing the places and things you do outside of work. Your Facebook says a lot about you because it shows the friends you have, the things you do, the places you go and the things you say. If you have things that your mother shouldn't see, then don't put them there. The less you have, the less your employer has to see of you, which is the best thing you can do. According to a survey of recent graduates by online privacy firm Abine Inc., "despite the fact that 69 percent of 2013 students still don't have a job lined up, only 16 percent proactively spend time improving their web presence". Don't be the person who doesn't care, be the person who gets hired. Additionally, employers should review their social media policy to make sure they aren't restricting employees' protected speech because you need to know what you're allowed and not allowed in order to be free to express what you want to say. They make sure employers are reasonable with policies, include employers' right to limit use of company equipment and to spend company time on non-work activities. These policies will be enforced consistently, so always be prepared for whatever happens
