Couple of years ago we got a new coworker who was really confident but just had this bad habit of making stuff up that sounds good to meet a deadline and seemed incapable of admitting that's what they were doing, so I just never gave them anything to do if I wanted to know something was done right, which is all of the time. No one in the office really talked about them.

Anyway, at a work conference today, we've been told that actually we should be using this lying coworker as much as we can and spending our time checking if what they said is sound as well as doing our own work. This is because it will eventually make us more productive even if it appears to slow us down to start with. The coworker is here to stay with the promise they will definitely get better at some point and all the money going to them will pay off at some point so we need to learn to get the most out of them.
