Maybe you have met them in your coach training courses as well: the "confrontation" lovers! They get really nervous when we talk about complimenting coachees, look for resources, address them in their resources first and talk about challenges instead of weaknesses, lack of skills, mistakes.
They prefer 'confrontation'..... ! (And they claim to be very successful when they 'confront' their coachees.) I explain that most people learn more if they are encouraged rather than criticized, (explaining the fight/fight reaction, reptilian brain etc..) But if it works with their clients that's fine, they probably do something that works.
I am curious: maybe SF coaching is not suitable for people who have a different style and it would not be authentic for them to coach in an SF way? What do you do when they are in your course?
