Really good question. The practical answer is that you would like to think they are talking to each other as they both are working for the Employer/Client. If they are using one of these on line administration tools (e.g. FastDraft) you would like to think the PM can see all the communications the Supervisor is raising.
So, contractually I don't think there is an obligation for the Supervisor to liaise with the PM first, but practically speaking hopefully they are both up to speed with what each other is doing.
