On 27 July, WMF declined to voluntarily recognize the US union. WMF stated that the union would need to pursue a formal NLRB election procedure. 404 Media viewed the WMF’s 27 July statement as using “very carefully-worded language common among companies and organizations that have fought against unionization”.
Not too spicy, but they at least acknowledge it.

I wonder just how much they’re relying on Trump’s NLRB to sweep it under the rug. I highly doubt they’re doing this in good faith.
