I personally ground in Wilmot’s End for my Strong-Backed Labour, but if I’m not mistaken the fastest way to get them is to grind your Docks and Orient connections up to 30, and favour the dock-gangs when their conflict card turns up. This will net you 4 Strong Backed Labour each time. You can also become a Rat Catcher to speed things up a little bit. Getting them through converting Stolen Correspondence isn’t bad either if you can get your Compromising Documents through the Velocipede Squad or Foreign Office.
