I can't quite put my finger on it, but there is something very odd about a non-unionized company like Burger King running ads touting the work of a fictional "
stacker's union" composed of tiny people building (up to)
1000 calorie hamburger sandwiches with scaled down heavy equipment.
I'm pretty
strongly anti-union, but it seems crass to suggest that your product is made using even fictional union labor when it most clearly is not made using union labor.
On the off chance some subjects of the Burger King are unionized, like truckers or meat cutters, I'm still pretty sure the employees behind the counter are almost never union.
