Arthur Scargill-v-M.Mouse!
Scargill, in the midst of the miners dispute, stated that the intention of the National Coal Board was to close mines and lay off workers. The NCB and the Tory government both denied this. In the end the mines went, leaving thousands of families destitute in areas where there was no other work (NB there are lots of call centres now!). Who told the truth, Arthur or the NCB.
As stated previously, workers have a right to protest, and the Conservative goverment brought in legislation that allowed employers to replace striking staff with other workers.
I suggest a search of Pprune with the word SCAB - I'll let you tell me how many threads you find where airlines have used scab labour in the pilots seat, and also what the opinion of the mass of Pprune readership is on this issue. Then come back and tell me that workers (and their elected union representation) do not have the right to industrial action.
