Maybe the union should consider bargaining on behalf of its members only and see what they can muster up for their membership base in regards to a new set of working conditions and allow the company to do what it pleases with the rest of the crew.
Maybe if the FAAA hadn't sided with the company during the very first round of EBA negotiations, they wouldn't have had such a dramatic downturn in membership!
Perhaps if those who left the union saw that you were in fact representing the employees rather than the company, then maybe your membership would increase.
It's your own fault that your membership has dropped. You forgot whose side you're supposed to be on!
