Tens of thousands of workers, from Hollywood writers and actors to hotel workers to UPS drivers, have taken part in the "summer of strikes." These kinds of collective actions are likely to keep going well into the fall, experts say.

Over 230 strikes have been recorded this year so far, involving more than 320,000 workers, compared with 116 strikes and 27,000 workers over the same period in 2021, according to data by the Cornell ILR School Labor Action Tracker.
