“Charities welcome help from ‘unretirees’ — not just as trustees but also to help with projects, such as presenting accounts in a better format for the board, negotiating building leases and other contracts, and mentoring the chief executive and employees,” said Victoria Tomlinson, chief executive of Next-Up, a resource for pre-retirement employees.
