General strikes (where an entire union membership nation-wide goes out) can and do happen, but not always, and, at least at this point, not in this case. Equity can more than make its point by pulling its members only from the most lucrative contract it is a signatory to. It doesn't add any pressure the to wealthy Broadway and Tour producers if actors from a constellation of small not-for profits around the US were to walk out as well. I suppose a general strike COULD happen if this thing were to drag on for a while, but as of now, there hasn't been any indication from the AEA that that's what they're planning.
