"Trust your people to do their jobs, and deal with things later if they don't, but trust them up front. "

Sounds simple, and it should be - but I've seen too many that do not. Instead of starting from a position of TRUST (hello, you hired them) - they take the X-Files approach and 'Trust No-ONE!'

Time is too short, and I'm too old - if there are questions of honesty or integrity, then it's a retention issue.
