Working Joes are durable but predictable. Early on, stealth is best. Use vents or distract them with flares. If combat is unavoidable, aim for headshots with the revolver or shotgun. The stun baton can temporarily disable them, allowing you to run past. EMP mines are highly effective, stunning them for a significant duration. If you have a pipe bomb, it can destroy them, but the noise will attract the Alien. In groups, try to separate them or use environmental hazards to your advantage. They are attracted to light, so turning off your flashlight can sometimes help.
