Point one... (On topic) - this is great news, and means a much better work product for Delta.
Point two... (still quasi-on topic) - One has to wonder if unions were aware, at the time of passing each, they forced their own obsolescence with the support of the FLSA, OSHA, EEOC, Minimum Wage, and other similar laws... One has to wonder if they realized, at the time, that the valid and important protections they offered would no longer be needed (thanks to the Gov't), and that in the future (now) they'd be simply negotiating and striking based on entitlements (pay, insurance, retirement, etc...).
I completely support an employee's right to unionize. I do not (IN ANY WAY) support a union's right to require such membership to work there, nor do I support any other dues collection method aside from individual billing. (No payroll deduction, especially no governmental collection, etc.)
