Preventable cardiovascular disease, cancer, arthritis, diabetes, mentalhealth disorders and disabilities affect more and more people as obesity and other underlying risks increase and our population ages.
The trust, which provides services covering mentalhealth, learning disabilities and addictions in Hull and the East Riding of Yorkshire, informed the union of its proposals on 10 January.
The charity said 50 volunteers, including many with mentalhealth issues or learning disabilities, would also lose their work experience placements at their depot.
