The Right to Moan?
I worked for Telewest a few years ago. At the time, they had an alarming corporate nazi thing called 'Living The Brand', the upshot of which was that you could be disciplined if overheard by a superior speaking in public (ie moaning at the pub) about how shit your job was. A few employment tribunals later however, it all went quietly away. Whether saying the same things on the Bad Scary Internets would be looked upon in the same light by said tribunals is debatable however.
