work sucks

It seems my department at work has over billed the government somewhere between 3 figures and possibly 4 figures. The witch hunt has begun and things have been pretty stressful. This is an internal audit of the last 6 months. Anyone flagged will be scrutinized as to their work and how their days were spent. Of course it is all the fault of "US" lazy union workers! Yesterday we were all called into a meeting and told to sign a form that stated we had had a training in time charging. Hopefully this is the corrective action the big wigs are requiring to remedy this situation. It is funny to me that the company can figure out how to take out our lunch time automatically, but can't figure out how to stop billing the customer (government) for that 1/2 hour. I know they would catch it if they overpaid one of us for our lunch. This seems kind of intentional to me that they would overlook something that has gone on for over a year with no one checking the billing to the customer.
