Responding to unwillingness - a management training course

How can you respond to unwillingness?  By saying, “You don’t seem very keen. What’s bothering you?”  If you talk about it you might be able to turn it around.  If you ignore it, you’ve no chance.  The safest approach, unless the person gives you an unambiguous signal to the contrary, is to assume unwillingness and talk about it.
 

You can develop and practise the alert skill you need to notice and respond to unwillingness on our highly acclaimed London UK management training course, “Skills with People”.
 

But how can you be sure this training in responding to unwillingness is for you?
