PLAYING HIDE AND seek isn't on many chief executives' to-do lists, but Nigel Howlett joined in while visiting Sunflower nursery in Cambourne. His trip was part of a scheme to give CHS directors experience of life on the front line. The housing association, which has 117 full-time staff and 291 part-timers on the payroll, provides affordable homes in and around Cambridge. Howlett runs it on sound moral principles, an 80% positive score, ninth among the mid-size NFPs in our list. www.chsgroup.org.uk
