Without wishing to revisit old arguments there are considerable differences between working H24 shift operational positions and working in offices on a regular weekday 9-5 pattern.
That is why I personally object to non operational staff voting on operational/shift issues, especially as most seem to have your attitude and will vote for the company line every time with no understanding or caring as to how this will affect others. Being operational, I would not expect to vote on issues concerning the great administrative empire down south.
