I hear you. I agree that union busting is bad. I support trader joes employees unionizing. I don't want their stores to close and those employees to be out of a job.
Any employer that's a union buster deserves to be boycotted until they close and something better comes along to fill the need (which it will do quickly). In truth, the grocery supply chain/warehousing being so strongly coupled with the supermarkets is the primary point of inertia in the US regarding grocery stores opening where they're needed. Most independent distributors only focus on restaurant contracts, because they can achieve higher margins there.
Curious as to what the union’s demands are. It’s my impression that Trader Joe’s treats their employees relatively well. I have multiple friends who work for them and are paid a living wage (in the Bay Area of all places) for working reasonable hours.
I only have one smaller chain grocery store in my area, and it's half snake oil targeted to old hippies. It's also three to four times as expensive because old hippies apparently have money?
