Really shouldn't have posted results, or polled at all. That information is only likely to make workers less likely to join, whether it leans one way or another it's likely to make the other side less likely to join. I would not join a union that is full of tories, full stop, I know most well-meaning libs that support labour wouldn't either. But I also know that tories wouldn't join a union if they knew it was like all lefties or whatever.

It's just not a good way to organise. It's publishing information that you know will cause division.
