No not really - my employers is my wife's company ( I have no shares or interest other than employment ) and the company maintains PI Insurance which gives usual client protection. One of the directors of the client company now says that if I were to become a director then I would then be deemed to have a service agreement with them and all the financial services provided by me whilst working fro my employer would be removed from the protection of PI Cover and Limited Liability. I dispute this as in my view my wife's company remains the contractor to the client and I remain an employee of my wife's co. I cannot see that any sort of contractual arrangement , implied or otherwise has been created by accepting a directorship.
By duty could you just confirm that attending meetings and commenting on reports - usual director fiduciary duty is not then an implied service contract
