Most ground crew don’t do this because they’re angry, dissatisfied or understaffed but simply because they don’t have the time to handle each single piece of luggage with care! We even had our fair share of luggage falling out of carts here at Brussels since it wasn’t properly secured.
We work with strict deadlines on when the last piece should be on the belt or the handling agency gets a hefty fine. Perhaps the developers could look into adding fines for you as the CEO when the performance of the luggage system is not on par with other airports.
