hecubus
General Specific
I don't trust automated workers (they may make a farm on the town). So in the later game I always have workers standing around at the end of the turn. I take them and make them go for a walk for 2 or 3 turns and when they are done, I'll send them back to where they came from. I suppose I could delete them, but you never know when you have to rebuild a tile and they are needed to reduce the quantity of the workshops in conquered land.
I'm such a control freak I never turn on automated workers, but in a recent game on a huge map I thought I'd set some of my single ones to building a trade network after I got railroads. Kept all my paired workers under my control to put RR on important plots like mines and lumbermills, and build improvements in recently captured cities. Sure enough, I find a fort on a gem plot within a city's BFC, and most eerie of all, a dozen converged on a spices plot at once to build a fort. Something hive-like about it, it creeped me out. At any rate, it's back to micro-management for me, and a few dozen workers sleeping on a central hill when there's nothing left to do.
