Georgina Jones (British Library) said the pay restraint of the last four years could not be allowed to continue.

Robert Phillips (Cangen Treftadaeth Cymru/Wales Heritage) said cuts were hurting the sector. Heritage workers were a “soft touch” when money was tight because they are so dedicated to their institutions.

Restructuring at the National Museum of Wales had brought fewer jobs at lower grades. At the National Library of Wales, staff have more responsibilities and extra hours but salaries are worth 20% less than a few years ago.

“Our goodwill cannot go on indefinitely. We need realistic salaries people can live off,” he added.

But Karen Render (Food and Environment Research Agency) proposed remission. Although she agreed with the sentiment, those in the heritage sector were not the only people suffering.

“We should campaign for a pay rise for all workers,” she said. Delegates agreed and remitted the motion.
