As a Londoner I get this, but… what else could they do? If drivers strike, that’s what happens. And now the government wants to close ticket offices too, because hey, no/one could possibly want to use them.
anyway, as for acting - I think the Equity Union is a pretty big deal in the uk but I couldn’t tell you what major work it’s done. No doubt it’ll be following this closely. A lot of American productions seem to film here now.
