Nine prison officers at HMP Manchester were disciplined last year for charges including inappropriate relationships with prisoners, abusive language or behaviour towards staff – and being asleep on duty.
Other offences disciplined by the National Offender Management Service (NOMS) during the period January 1 2012 to December 21 2012 were unprofessional conduct, making/prompting false statements and performance of duties.
The penalties dished out by NOMS for the nine prison officers concerned ranged between dismissal and a written warning.
A Prison Service spokesperson said: “The overwhelming majority of staff at HMP Manchester are hardworking and professional.
“Staff whose conduct falls below what is expected can face disciplinary action ranging from a warning to dismissal.”
The data released under the Freedom of Information Act does not include cases where staff have resigned from the service before any disciplinary proceedings have been instigated.
HMP Manchester, formerly known as Strangeways, is a high security prison which houses around 1,200 inmates and employs more than 800 members of staff.
