Bad idea. Consider how much time people/employees waste on Facebook every day. What company would encourage their users to login to Facebook during work hours? The notifications will send them to the news feed, which becomes a black hole the moment one starts scrolling down the page

    Facebook
    This massive social network deserves a mention on its own. 
    This makes up 7% of the websites accessed at work and is a
    major contributor to all the wasted time in the workplace.

    1. Social media sites. Not surprisingly, visiting social 
    media sites is the black hole of workplace productivity. 
    Facebook is the top social destination, with 41 percent of
    survey respondents logging in from work every day. Facebook
    is not the only culprit however; LinkedIn, Google+, Twitter
    and more recently Pinterest all claim their share of 
    work-hour traffic.

I wouldn't work at a company that used Facebook as an internal communication tool, because it would encourage massive time wasting.

Isn't this a different feed from your personal account?

But still, I understand how it could encourage checking your Facebook account even more.

I don't know. I didn't look at the design closely. I stay away from Facebook as much as possible. The more I stay away, the more things I get done in life.

They have a strong incentive to keep people on their site for as long as possible and they are extremely good at it, so I think it's a huge mistake for companies to send employees anywhere near it.
