Who pays the strike fund? You. Whose dues will most likely increase because of the strike fund depletion, yours. When i say profit, I mean they "at times" use strikes to prove their worth. To prove that dues you pay are for a reason. If all the union did was show up and negotiate your contract every 3 years, I'm sure you find little use for them. So they need the issues between employer and employee to justify their existance. Using disproved ULP charges is just one of many tactics used to justify taking your money. They profit, because they have convinced all of you that the charges were true. Therefore they keep earning money from your dues. But now they have been disproven. Will you ask for your money back? Probably not, and therefore, the union profits.
