The company has joined The 5% Club, a scheme designed to get the UK's public and private sector companies to commit to having 5 per cent of their total workforce as apprentices, sponsored students or graduates within five years.
Glendale specialises in nine green service sectors: landscaping, grounds maintenance, arboriculture, estate management, cleansing services, vegetation control, woodland management, the supply of plants and semi mature trees, and golf management.
Andy Corcoran, managing director at Glendale, said: "Youth unemployment in the UK stood at 15.6 per cent in September last year. By joining The 5% Club, we are playing our part in addressing this problem.
"We currently have many apprentices with us, all of whom are invaluable to our company and we're excited to welcome even more of them in the coming years. We are proud to be part of The 5% Club and are looking forward to making a positive difference to our next generation by providing them with the professional qualifications and practical training needed to build a career."
The 5% Club campaign was initiated by defence technology company QinetiQ in a bid to help the country remain at the forefront of innovation. As a member of The 5% Club, members are asked to publicly report their progress in their Annual Report.
Dr Sam Healy, programme director of The 5% Club, said: "We're delighted to welcome Glendale to this initiative. The company's existing efforts to invest in the next generation are greatly welcomed and together we can strive towards a brighter future for young people in Britain."
