Re: multiple teachers in one dojo
I share teaching duties at a dojo with one other instructor.
Do we disagree?
Yes, but in private where we come to a mutual undertanding of what is best for the dojo/students. We have somewhat different styles but we acknowledge that and use it to the students benefit.
Is ego/rank an issue?
Nope. He is my sempai and he makes the final call. If I have issues, they are my issues to deal with not his or the dojos issues.
