Facebook has rolled out a new feature: businesses can now post job listings on the social network. After first being tested last year, business pages will now be able to post job openings to their news feed. Users will be able to apply to vacant positions under the "jobs" tab on the company's personal page. The feature is now available to all United States and Canada-based business pages. Facebook could start monetizing from the feature if businesses pay to advertise openings in order to reach more people in the feed.
