The row over a privately funded replacement for Edinburgh Royal Infirmary continued into the final days of campaigning for the Scottish Parliament elections.
Scottish health minister Sam Galbraith was forced to say publicly that lower-paid workers would have pension rights under the private finance initiative scheme.
Labour had been attacked by one of its own spokespersons, John McAllion, over PFI. He said staff on less than£16,000 would lose pension rights, and that PFI was 'eroding' terms and conditions.
John Lambie, Unison's Scottish head of health, said it remained opposed to PFI as a method of funding Scotland's public services, whatever deal was reached on pensions.
