“More than 140 staff at Barnet Council’s Regulatory Service’s Department will take industrial action, in a bid to remain directly employed by the council.”
Proof perfect that the council workers know they are overpaid.
If they thought they were being underpaid then of course they would be clamouring to be in the private sector, where wages must be higher (must be, for that’s the only way that the public sector workers can be underpaid).
That they will strike to remain in the public sector is thus proof that they consider themselves overpaid in the public sector. It is an acceptance that a private sector company would be able to fill their jobs at lower wages, isn’t it?
Remember your basic economics: revealed preferences. Look at what people do, not what they say.
