Can a person be an employee of Unite and also still be a branch secretary of a sub-union that represents employees of a company he no longer works for?
That's a bizarre scenario.
On the premise that this dispute has stretched the definition of bizarre to new boundaries, the answer is possibly yes!
However, I agree that DH's position is, dare I say, unusual ... and
undoubtedly being analysed by BA's legal people.
In fairness, who are Messrs Wooley and Simpson employed by? They represent employees who are members of the diaspora called "Unite the Union".
