When I left last year we were still under directive to bill everything from training to other UK account expenses to the BAE cost code. Apparently BAE were being billed for every UK staff member but this was not actually the situation in the ground with the run and project areas being staffed by skeleton crews consisting of juniors with no security clearance and gradually diminishing veterans who were leaving for other better paying roles.
When I challenged this I was told explicitly by management and colleagues not to question it as BAE deserved to be expensed out for everything because of their treatment of our staff as whipping boys. But thinking back this seemed incredibly sketchy
