King's College NHS Trust is tackling recruitment difficulties with a raft of initiatives designed to attract staff and get them working towards qualifications.
The trust said it realises there is no easy fix, but is focusing attention on recruiting locally in a hope this will help the community and provide a more stable workforce.
Mike Griffin, HR director at the trust, said traditionally a lot of investment was made in training professional staff, while other sections of the workforce were ignored. Now, he said, there was a recognition that there were unqualified people with great potential.
"The Trust now recruits locally," he said. "And a changing age profile toward older workers, means they are more likely to stay with us."
As part of its new strategy, King's runs open days at Jobcentres, provides extra support for those in new roles, is focusing training in hard to recruit areas, and offering financial sponsorship to people in training.
In five years, the trust has seen nursing turnover drop from 22 per cent to 13.3 per cent and vacancy rates also drop markedly.
Jane Matty, community development worker and manager of the King's in the community programme, said educating schoolchildren about career opportunities is helping sow the seeds for future employment.
"All work placements are now reserved for local children," she said. "It's helping to contribute to the social and economic regeneration of the area."
