I was reliably told by numerous grade school teachers, particularly my 8th and 9th grade English Composition teachers, that "in the real world there's no such thing as late work," as they reluctantly let us turn in late assignments with a 5% markdown. Fast forward to now and just about all of my contractors and their subcontractors submit multiple requests for contract extensions during their contract performance periods. When I deny (most of) these requests, they have no shame finishing late anyway, and work continues after the contract ends. So much for no such thing as late work in the real world, Mrs Warren and Mr Sumner.
