Strikes hurt a lot of people other than the parties involved -- actors, wardrobe, hair and makeup people, ushers, concession workers, box office personnel, plus restaurant workers (cooks, waiters, bartenders), retail workers, cab drivers, etc.....
And yes, it's a shame, but there's little than can be done. Actor's Equity (as well as most of the other theatrical unions) have announced their solidarity with Local One and have even encouraged their members to join the picket lines. Understand, that part of the reasoning behind that may be that Equity's contract with the League is up next year and I'm sure Equity is assuming that its gesture now in supporting Local One will be returned by the stagehands next year, if need be, when the actors have their own renogotiation with the League. Similarly, four years ago when the League threatened to bring in computer-simulated orchestra programs to replace the musicians, that issue was quickly put to rest when the actors refused to perform with those programs and joined the musicians in solidarity in the strike against the League.
All the unions seem to support each other in these situations and that support will continue until there's a resolution to this strike (mind you, as more actors, musicians and other theatre professionals continue to suffer financially while they're out of work, you can be sure that their unions will privately be putting pressure on Local 1 to settle this dispute ASAP).
