So a chef for Sodexo? Nice bit of obfuscation there so which of the Crown Strategic Suppliers do you work for? They are not a secret https://assets.publishing.service.g...1-19-strategic-suppliers-crown-reps-draft.pdfa member of a company
And this role of yours? HR Manager? Finance Manager? Project Manager? Operations Manager, H&S? IT? Sales? Marketing? Security? Executive Board Director? Non Exec Director?. There are many more, my point is very very few supply chain employees know or would see the granular detail to make the assetion you have and of course if a Commercial Company loses a contract it is always the customers fault and never the ineptitude of their own staff.
Just in case MoD 'Strategic Suppliers': 19 Strategic Suppliers. These are Airbus, Babcock, BAE Systems, Boeing, Capita, Cobham, DXC, General Dynamics, KBR, Leidos, Leonardo, Lockheed Martin, MBDA, QinetiQ, Raytheon, Rolls-Royce, Serco, Thales, and Ultra-Electronics.
As for your other suggestion if you expect any user on here to disclose OFFICIAL (Whether SENSITIVE or not) or information that may border on SECRET on this site you need to take your head for a shake.
