Industrial action will be more likely as result of the bill - STUCpublished at 10:29
Dave Moxham from the Scottish Trades Union Congress says it is fundamentally wrong that an abstention should be considered as a no vote in a strike ballot.
Mr Moxham says there is essentially a three part democratic process to achieving strike action.
He says unions take a view to how likely the third part, industrial action, is going to be successful.
Mr Moxham says there is a lot of misunderstanding of the process and there are quite a lot of stopping off points in it.
The government, through thresholds and other changes, is making that situation a sharper one for unions, who will have to make decisions quicker and more aggresively, he says.
Industrial action will be more likely, says the STUC representative.
