Sir Digby Jones, the ebullient director general of the Confederation of British Industries (CBI) and solicitor, has written 'a celebrity letter to the editor' in which he tells us that he is going to spend a day working in the CBI's postroom. Sir Digby, who is taking part in aid of Marie Curie Cancer Care's new Back to the Shop Floor initiative, calls on senior staff to do the same. Arguably staff should make donations to ensure the senior or managing partners at their firms do not become the tea lady or the postman for the day - otherwise, they might learn what is really happening in their firms when sifting through the letters and faxes or having a gossip on their tour of the office. Joking apart, to learn more, go to www.mariecurie.org.uk/backtoshopfloor or telephone 0800 716 146. Sponsorship money will go to the charity's annual Great Daffodil Appeal.
