From the article ...
Among Apple’s earliest tactics, a bold one even by corporate standards, was to offer all but the Towson store workers new educational and medical perks, saying that the nascent union would have to negotiate for those perks while nonunion workers would be able to enjoy them immediately. The IAM CORE members claimed it was a “calculated” move by Apple, timed just ahead of a second retail union vote at a store in Penn Square, Oklahoma
Luckily, the bid failed and a majority of Penn Square’s Apple workers chose to unionize.
Apple’s ugly maneuver echoed that of Starbucks corporation a year later. The coffee giant increased hourly pay for all but its union workers. The NLRB also ruled against Starbucks.
That's some shitty psyop moves by those two companies. Glad they didn't work.
