A couple weeks ago at work, I received an email stating that we now have a company suggestion box.
A couple weeks later I received an email about how we've had the suggestion box up for a couple weeks, and haven't received any suggestions.
I took it up on myself to remedy that.
About a day later, I got an email from HR saying that "MOTHERFUCKIN TITEEZ IN MY FUCKIN FACE" is not a valid suggestion...and to please, "refrain from vulgar suggestions in the future".
Later that week, another email was sent out, reiterating the purpose of the suggestion box, and that in the future, any profanity will result in disciplinary action.
I have since held off on any future usage of the suggestion box.
