Teenagers and job seekers are always advised to be careful what goes on Facebook because employers can find this and may not hire you because of it. Grown men already in the business world should already know that the reverse is also true, those looking to be hired or do business with you can find your Facebook postings and not do business with you. Facebook seems to have ratcheted up his outspoken manner to the nth degree. Unfriend him yes. And if the bills rely on his job you may want to start looking for alternative funding, he may not have his job for long.
