Prismatic

30 BBC staff had their emails monitored by the corporation's Investigation Service in 2012.

They categorize the reasons thus...

•  Bribery 1
•  Computer Misuse 8
•  Miscellaneous Enquiry (eg. Disciplinary cases) 4
•  Enquiry by Police 1
•  Fraud 6
•  Harassment 1
•  Information Leak 4
•  Malicious Communication 3
•  Theft 2

“The BBC rarely monitors staff email accounts and only in exceptional circumstances where it is reasonable, necessary and represents a proportionate response. Monitoring of email accounts is invariably undertaken in relation to criminal or disciplinary investigations and staff are aware that monitoring can occur.”
