David Melding has actually just touched very briefly on the Unison event that took place recently. I wonder, First Minister, if you would join me in welcoming successful initiatives like the Unison mental health in the workplace conference that was organised in the Pierhead building, which I think once again showed the central role that trade unions can play in helping to tackle difficult issues in the workplace and demonstrates the valuable role of social partnership in delivering better outcomes for issues like tackling mental health in the workplace.
