This comes from the FB help desk -
If you've been blocked from sending messages on Facebook, it may be because you sent a lot of messages recently or people reported your messages as unwelcome. Make sure to use your real name and picture to help the people you're messaging recognize you.
Please also keep in mind that this block is temporary. You can still use other Facebook features to connect with your confirmed friends while you're in this block.
Once your block is over, please only send messages and friend requests to people you know personally. To learn more about our policies, please review the Facebook Community Standards.
Note: If you're blocked from sending messages, you may also be temporarily blocked from sending friend requests.

If your manager blocked it - it's because this manager does not want it used where you are and it's not part of your job to be using FB. You should not try to unblock it! Use a smartphone if you "must" connect to FB during the day when you are allowed to.

go to tools-- options-security--then select block or unblock sites

Try FB through this site http://www.surf24h.com/ if it is blocked you should be able to see it.

Hope this helps!
