There are some 2,700 staff employed by hon. Members using standard contracts. About 70 new staff are appointed each month. The Green Book requires Members to lodge contracts and job descriptions with the Department of Resources. Following a recommendation by the National Audit Office, the Department carried out an exercise in 2007 to establish how many contracts were not held as required by the Green Book. At that time 371 were not held. A similar exercise in 2008 found that 218 were not held. No information is available on how many of these had been lodged but mislaid. The Department has taken action to request that copies of the contracts be deposited in accordance with the decision made by the Members Estimate Committee on 20 October 2008.
