I don't know why people are insisting on proof. An employee is an employee, so they represent their employer in regards with workplace related issues.
That is how Meghan had to apologise, JK was working for her. She did not speak to FF authors, JK did. But he was working for her, so she did co-operate in the eye of the law.
JK works for W, he is representing a work related issue, so W did testify against MM .
In both cases using JK as the mouthpiece.
When Priti Patel or any gov minister says something, it is from Boris and the government, unless bojo comes out and explicit denies it. They are his employees, there to represent him and his government.
When P Valance and C Whitty, used to come out with guidelines they were representing bojo and his government, so we were following them. Unless bojo would come out and denounce them (like he with Cummings). Other than that, we are following guidelines as set out by bojo and the government.
When you go to Barclays and Sue at the counter tells you, you cannot get that loan, Barclays refused you, unless Barclays comes back and says, well no, Sue is talking rubbish, they then open an enquiry into her, and punish her and give you your loan back. Barclays refused you.
That is just how things are in the work place.
