"why some people think that charity staff should martyr themselves to their cause"
Was that not just one person ?(I caught the drift of something about 10% reduction), and if was only to apply to a few at the top, on 80K+ think it might be a reasonable reduction, just as I agree with Talkinpeace on the 7x salary of lowest - it's hardly martyring, but might weed out some of the marketing and other people who may be on a cushy, less stressed, number but getting a private sector salary, and probably {through exposure of salaries many of us dream of} alienating many of the volunteers, and people who donate, when there are revelations about how much get's absorbed in administration and salaries. I suspect Barnardos is far from the 'norm' - the ones to look at are those with turnover below 5M where larger portions might be used in "admin".
Some of the 'campaigns' for funds are going into what I consider unethical territory, with expectations of people writing a will in favour of a charity, and "suggestions" as to monthly donations, not leaving it to the individual. Such things make people view charities (all charities, not just the worst offenders) with a lot of suspicion and could lead to a decline in funding. Sooner some charities wake up to this fact, the better things will be.
