That's just a stupid statement. The country has a 9%-13% union rate for workers depending on who you believe and those low numbers indicate that majority is non-union and therefore controlling. That Right to work crap is a race to the bottom and if it was implemented, would guarantee that the general public fight for pennies their whole lives. If not for the unions, the rate would be even lower for competing companies that are non-union. Fedex would make dollars less an hour, construction companies through prevailing wage jobs, etc.
The last strike at UPS was 1997 and this contract (if passed) guarantees another 5 years of work. The math says that is over 32 years. If Yellow(really YRC) goes out, every other freight company will easily take their loads with no strain on the system. I hope it goes to our brothers in TForce or ABF to name a few. There are only about 13K YRC union employees. Freight companies go under every year (union and non) as big as YRC and the American market is barely aware. The goods still make it to their location on time. The scab owner/ operators are the reason the rates are down.
If not for the threat of a UNION strike, there would be no vacation, sick time, holidays, workplace safety, middle class, etc. In a time where company profits are soaring and wages are remaining stagnant, more Union presence is required instead of less.
