Ok, now you post something meaningful and you know how to post like an adult and discuss/debate, good job there.
And, It's not a mere speculation, the club announced a while ago the new football structure, and plenty of reputable journalists spoke about what it is too, that is what is informing me so far, and of course no one knows what is the real day to day activities of these people (Murtough, Fletcher) but we can gather some info and make an informed/educated guess here.
So, as mentioned above, the football structure exists before RR's arrival, and RR in his current role is the "Interim" Manager of the first team, no one is being forced on him, he can easily ask Fletcher to remain away from training and from match day group, also RR was allowed to bring in 2 coaches (Sascha & Armas), which shows the club is giving whatever support RR needs to do his current job as the Interim Manager
Regarding RR's job after his interim stint, he will continue on as a consultant for 2 years, this is the information we have, and we can then say for example, RR's remit in that consultancy role is to provide advice to the Football Director (Murtough) for 2 years on matters related to the football side of the club, a consultant, by the nature of their role, provide advice only, and maybe try to influence the ones in power, however, the decision-making power is with Murtough or Arnold, for example, in the summer, RR can tell Murtough that Fletcher is not needed and has no value to the club going forward, it will be up to Murtough then to decide what to do with Fletcher. (keep him or let him go).
