75% didn't vote yes well many didn't vote no either. So what can you determine?
This is my point, Safety Concerns, unless the ballot is worded with a number of options, as described by another poster, the result must always be calculated on the votes cast, since no one knows the intention of the non voters, so the union are being absolutely correct in saying 3-1.
I also with the statements about governments being elected on very low turn outs - interestingly enough, in Australia, voting is mandatory.
Maybe that is a fairer fix for union ballots? Vote or be liable to legal action.
