My local went on strike once in 2019, it lasted one day and everyone who picketed got $200.
Last year we threatened to strike, had an authorization vote, but our signatory contractors association wanted nothing to do with it and we basically got everything we asked for with no work stoppage.
The deal in my part of the country is that what with the CHIPS Act, there’s literally billions of dollars on the table and our signatory contractors can’t afford to get bogged down in labor disputes.
The upshot is that it leaves the unions sitting pretty since they can’t access these incredibly lucrative contracts without using highly-trained union labor.
There’s more to do with EMRs and the like, but I won’t bore you with the details.
