I think the next widespread labour action will be focused on benefits - it'll pull in both of the factors you mentioned (increased earnings and wealth redistribution) since I don't think any labour gains will ever happen without those factors (and the first factor necessitates the second factor). But I think the focus will be lowering employee stress by advocating for stronger requirements around healthcare and reducing the workweek.
