I’ve been seeing posts like this for a while recently, where the sentence is valid, but super confusing. I honestly wonder if it’s some AI writing issues, or too many places have fired their editors for AI.

I believe it could be rephrased as “the RATE of perspective buyer blackouts are increasing” maybe meaning once people look harder at the numbers they start feeling unhappy with the deal.

Having other areas of your field with better pay/conditions/benefits can put more pressure on even non union places. Since there will be better contions elsewhere, there will be an expectation of a level of compensation/more people looking at those union places, requiring even the non union locations to at least increase something to compete for talent.
