The more people earn, the less charitable they become, according to a survey of staff in the UK.
Human resources consultants Black Mountain discovered that if employees were given a £5,000 bonus, 29 per cent said they would give a portion to charity.
The figure fell to 21 per cent if their bosses awarded them a £50,000 windfall. If the bonus was £100,000 only two per cent said voluntary organisations would receive a slice.
In comparison, 11 per cent would go on a shopping spree and 15 per cent would buy a new car.
"It's important for employers to understand their employees' motivations - and this wouldn't appear to include charity for the better paid employees," said Steve Nuttall, European regional director at Black Mountain.
Last week, Lord Joffe proposed a national benchmark for giving, set at 1.5 per cent of wealthy donors' income.
