As a Crown employee, publicly voicing views, concerns and criticisms of the Civil Service tramples over the principles and standards of behaviour that Civil Servants operate under.
You, sorry, your friend is a public servant, there to serve the public, who are here, reading information you are publishing referring to colleagues and the work of your employer in disparaging terms.
It’s also a direct contravention of Civil Service Code of Conduct/Standards of Behaviour and CS Management Guide, the former the basis of your employment contract.
