I am aware that the industrial relations issues at CS go well beyond pay, and that the dispute about pay may have been the tipping point for staff after those other issues, especially under Covid conditions.
However, I also stand by my observation that anyone working for a private sector employer who claims to prefer the prospect of their role becoming a public sector role needs to think very carefully indeed; the government is not noted for being a generous employer and is frequently more, not less, inclined to suppress wages in it's own interests rather than look to pay the going rate.
