Seen that happen in a major UK aircraft company, at the end they only had one aircraft in, a full workforce to work on it but were banned from doing so and a hangar full of connies brought in and doing the check... Turned out some accountant had figured out it was cheaper to have contractors do the work than their own staff, but never took into account the company staff were still being paid to do nothing on top of his cheaper labour..
It folded shortly afterwards.
