In organisations, people generally give you a 'heads up' when something is about to go badly wrong and they are hoping to rapidly disassociate themselves from the issue by apparently giving you a full briefing. You are often given a 'heads up' before stepping into an ambush meeting, a hostile reception at a conference or when HR have realised the wrong slide-deck containing full salary details has been cascaded to 2224 employees. While you are being given the 'heads up', most are keeping their heads down, checking their SmartFone for an escape route.
