He did not have them "On Edge". Riker described it as "Having everybody wound up so tight... there's no joy" Which is about the most ludicrous thing I've ever heard
All he did was ruffle a few senior staff feathers, & take some people out of their comfort zone. The main objection of anyone on the crew was that business as usual should be good enough for Jellico. It wasn't, & since Jellico was conducting a mission direct from Starfleet... Boohoo... Get to work
It's not just Riker...the near telepath also expresses confusion about his Jellico's orders and says that "He doesn't know what he's doing...." Or something like that.
