The archival assistants do not know how lucky they are with their boss (if in nothing else). Jon let Martin sleep at work, sent Martin and Tim home to look for the Not!Them alone, got three marks searching for info to help them save the world, died for them (arguably. at least to save the world, if not specifically them), performed emergency surgery on Melanie (not a good thing to do but the best thing), told Melanie how to quit, rescued Daisy who’d nearly killed him, and rescued Martin.
All this while they’re being very rude towards him. Daisy tried to kill him.
