I'm s/e and am about to take on a client but they aren't working to my deadlines (which is essential for their progress as is their enthusiasm.)
I gave a deadline two weeks ago for them to complete paperwork, needed 2 days before our meeting because I need to read it and do prep. I said in writing' please complete as soon as you can and no later than 'date'. (today)
They still had not emailed it by 9pm.
Would you personally think a deadline was end of play on a working day- ie 6pm latest- or midnight?
(There is a back history of them not confirming an appt within a deadline so I cancelled it and this paperwork is prep for the re-scheduled meeting.)
