You know...
You know what I mean...
Do I have to explain it...
I shouldn't have to spell it out...
You shouldn't have to be told...
It's obvious to anyone with half a brain...
Why do I have to explain it to you...
Maybe some of these statements have merit in an established, long-term working relationship when you've invested plenty of time and thought in articulating, setting, clarifying, and negotiating expectations, building a common language and common mental models...working together.... exchanging two way, timely and helpful feedback....
On the other hand, if you're using these phrases in the first 6 months or first 3 or 4 work assignments with a new employee, vendor, supplier or contractor (no matter how experienced they are), having spent as little time as possible together, having engaged in mostly one-way communication and critical, even offensive, feedback... then you're expecting them to read your mind!
And that, will, predictably, set you both up for failure, raise your blood pressure and their defences, their stress and frustrate the heck out of both of you!
