Probably not as much as you'd expect. Shit will just shift, and the change will be slow.
What I see is for the past 1-2 years, workers actually had the upper hand for a very short while...with demand/salary increases due to labor shortages coming out of the pandemic lock down. So companies were spending at all costs. Now that demand is softening, companies have the upper hand and are starting to clamp back down on costs.
You think the Big3 are going to give back what was gained from their buyout? Fuck no. You want more pay? Work longer. World-wide layoffs are coming as demand continues to soften. It will build upon itself. And corporations will continue to push for higher margins throughout the "downturn" they have created.
This strike is actually well-timed from the corporations' point of view. Strike will prolong, Big3 will cut production, suppliers will in turn cut their production, leading to rapid cost cutting and layoffs in the supplier space.
I'm sorry, but the workers ain't gonna win. They've never "won", so why expect anything different?
