I thought the situation was union protection of incompetent staff, in which case ridicule from colleagues &#x2F; friends, lost pay through striking, and having to listen to the kind of union boss who supports incompetent staff.<p>But for a significant change in working conditions (which introducing cameras seems to be), then I&#x27;d expect the more moderate union to argue this too — if that&#x27;s what the members want.  It might take a lot of negotiation.
