I can agree with you in some respects here. But I spent a lot of time in the automotive sector, and it's a very real and common reality for non-union folks who spend time bumping docks at assembly plants. I've seen it take three or more hours to unload a full load of racks at GM facilities if you're with a non-union carrier.
I'm not saying favoritism doesn’t exist at FedEx. But perhaps a better way to convince people to vote yes would be to, in circumstances such as these, help your hopefully future brother out instead of making him watch you get rewarded for your brotherhood when he was there first. Demonstrating the perks of the brotherhood will be lost on a guy who's been sitting there waiting for a union man to get off his break.
