No, I don't get your point.
In industrial action, all union members get a vote, regardless of which way they vote.
Three 33% workers going on strike has the same effect as one full time worker going on strike.
The only difference I can see is that it might take a little longer for 3 x 33% strikers to lose staff travel, due to rostering patterns.
A big rabbit hole, methinks.
