I’m a marketing consultant. The accountant/admin manager (who controls the budget, pays my invoices, and does most of the selection of which consultant is used), has told me to stop CCing the marketing director on project progress and information.
I report to this marketing director.
In fact, the admin manager didn’t even tell me this directly. He told his secretary to tell me, so I assume she will be blamed if it gets back to the Marketing Director that he is intentionally being kept in the dark.
