Dear Ploy,
Many thanks for your email. I hope you did not misunderstand my comments this week. I think we need to work as a team and improve communication especially in a situation of problems and if Tim seems to not be willing to follow your advice. In such a case we should talk directly. Please, also feel free to come to me.
I believe we should talk more details on Monday when I am back.
I agree to follow your plan but would like to talk a bit to understand the full picture.
Looking forward to seeing you Monday.
