See, your response is a red flag for me. It tells me you'll treat your employees like shit and talk down to them if they express their feelings like OP did.
I wouldn't accept a job offer from anyone who has a problem with someone writing a blog post about their experiences working for another company, good or bad.
People are too quick to act as if companies have this protection and that as employees we have to bow to them and cannot say anything negative, but in a heart beat companies will drop employees like yesterdays news.
This is a two way street and we has employees have just as much rights to express our disinterest and experiences with companies we worked with too.
