If I would be an employer, thing that I want to see least would be Facebook. From my own experience I know that Facebook is mostly synonymous for not doing anything. you write to one or two people. Browse few pages and suddenly. Your working moral is all the way down. Facebook can be this but also the very thing necessary for your job. It is amazing but Facebook At Work will be available to purchase in few weeks. Facebook At Work have been tested for more than two years now and it seems that it works well. If you want to buy Facebook At Work for your company you will have to pay for every employee but it should not ruin you.
