Good luck with the protest!
Regardless of the mess Wirral Council have got themselves in, that is not the fault of their rank & file workers, the terms & conditions of whom are rightly considered possessions.
Attacking their possessions is the same as the government saying "we are a bit skint so we are taking your television & laptop"! Nobody would reasonably put up with theft of their possessions, and Wirral Council workers are no different.
I salute their fight!
