The cost of the product has nothing to do with Safety per se. If the sectors or control position is properly manned. Now, the pay will go as low as those who are doing the job allow it to go. It depends on those of you who have negotiators on just what they are going be willing to give up to keep the membership working? For those who work at smaller towers and you have far fewer numbers to replace, it might be easier for that provider to replace you if you are doing an individual (facility) contract. If you are doing it for a country, it might be a bit more difficult for the provider if and only if you have the right to strike and IF the courts are going to uphold it.
It's all what you are willing to fight for, and also how much of your union dues you are willing to spend on the fight. Trust me, to do the
PR and the lobbying that you are going to need to just KEEP your pay is not going to be cheap... As we say to our members here, "give to the PAC (political action committee fund) like your job depends on it."
