If Apple were to offer a better deal, the employees would vote for Apple. Apple right now has to offer a decent package just to attact people to apply to work in the store, Wait until the economy goes down and then Apple non-union people will see all the good benefits cut and many fired with no warning.
Apple already out pays comparable retail jobs, provides better benefits, and has a stellar employee stock purchase program. However, many Apple Retail employees have never worked elsewhere and just think "union = better" as part of their life views.
Hell, I've seen some Apple Retail employees complaining that though they are paid and treated better than any comparable market jobs, "the union" will get them even more than what is competitive.
I worked for the fruit stand, and my benefits were better than I had at a comparable government job. The pay (albeit with more varied hours) outclassed government employees as well.
When one of the unionized stores eventually strikes and ends up in arbitration, many unionized employees will be in for a rough surprise when an arbitrator rightfully concludes that demands for compensation and benefit packages that are above already "over-market" conditions is unreasonable.
And to see that the employees want "profit-sharing" when
Apple has the best ESPP I have ever seen is freaking absurd. An employee can put 10% of salary into Apple Stock which they buy at 15% below the lower of the purchase date price or the price 6 months prior. At minimum that's a 1.8% "bonus" if an employee sells on the date the stock is purchased if the stock stayed flat. If the stock gained 10% over that 6 months it's a 2.8% bonus.
If an employee making $46,000 started ESPP on Jan 1, 2020 and maxed it out but sold as soon as the stock was bought, they'd have turned $9,200 into $13,000. However, if that same employee kept the stock, they'd be at $14,100 today. If an employee started ESPP in Jan 2019, they'd be doing incredibly well as those first stocks have almost tripled.
