In episode 5 of the anime Hellsing Ultimate, the leader of the best organisation in the world in slaying vampires is surrounded by vampires ♂️. She isn’t nervous one bit. She then gives her right-hand man, her butler named Walter, the command “ Walter, to work.” Walter then kills all the vampires surrounding her.
I very much would like to know how to say the command “..., to work.” in French. Does anybody know? 
I first thought that “Walter, to work.” is short for “Walter, off to work.”. But I don’t think this is true because I feel like the command “Walter, to work.“ is formal whereas the command “Walter, off to work” is not. I feel that this is true because the sentence “I’m off to work.” isn’t formal at all.
Lol so again , how do I say the formal command “Walter, to work.” in French?
Thank you for your help!
