a bit of business sense means you know which buttons to press on the management.
Naively dropping into discussions " but we'll be covered anyway under our insurance, won't we?" or casual (but distinctly audible) cooler conversations "there was a news item in the paper about an accountant in a company who got fired because of some mixup - and apparently if they'd held backups he'd have been OK"
