What's been happening in my firm is that a group of people of a relatively senior level (ie manager and above) have been trained by I think people from the firm, but who have been trained themselves by external people.
There are about 15 people involved in doing the coaching. They have had 10 days of training where they spent the initial few days learning about the process and themselves (quite touchy-feely I think) and then about how to coach others.
The idea seems to be that it is not necessarily business related, although it could be. Any subject (ie personal or professional) could be covered in a session and it is up to the person being coached (the coachee?) who determines what is talked about.
It is important for the coacher to not put their personal feelings into what happens at the sessions; this is why the group being trained had a few days at the beginning to find out about themselves, so they could make sure that they don't feel the need to explore that when they are coaching (or something like that).
It is being done on a trial basis in my firm, in one office, and is completely voluntary. I don't think here it would be taking the place of training (as our field of work requires continual training in not so soft areas) and I also think that what happens in sessions is kept confidential.
The idea seems to be that external factors can affect your performance at work and that my considering the whole picture, people are likely to enjoy work more and therefore be more productive for the company.I'm not sure how well it has been working in my firm (especially as I have moved offices recently). I think the idea will be to extend it across the whole firm in time.
There has been some division between the people who are coaching and the people wh are being coached - generally on the touchy feely aspects of coaching. Not having actually experienced it myself, I can't comment, but it seems that some people are closing their minds to it before they have tried it, IYKWIM.
Hope that helps a bit; if you want to know any more, please feel free to CAT me and I will tell you anything else I can think of .
