There are two types of organisations:
Opinions are welcome
Opinions are unwelcome
In the first:
thanks for taking the trouble to think about this and letting me know how you feel
I really value your feedback, even though I might not always agree with it
I’m going to listen to what you have said and take that into account in my future plans
don’t hesitate to share further thoughts
if it’s OK – in view of the fact that you have expressed an interest, I may enrol you as a sounding board
In the second:
who the hell are you to tell me that?
have you any idea what really goes on?
I’ve already thought of all those things – do you think I’m stupid or something?
when I need your opinion I’ll ask for it
until then – please MYOB
