Why don’t unions advertise?

In my many years, I have never seen a union advertisement—and ad that would drive someone to inquire into unions, or one that is generally pro-union that attempts to dispel some of the anti-union garbage that is pumped out by the Walmart and Home Depot, etc.

It seems like it would be a good idea to showcase unions to non-union folks—to try and promote the concept and show the good they do. But, here we are. The only union messaging that makes its way around FL is negative. It’s the same tired anti-union rhetoric that gets pushed around by Amazon and such.

What stops unions from advertising?
