"Worker's World" is for people who think they've got it rough.

It's at the Baltimore Museum of Industry, which is about a mile from Harbor Place -- where people used to work for a living and now come to play. To find it, follow the diesel fumes down Key Highway, past the Bethlehem Steel shipyard and into the still- working part of Baltimore Harbor.

"Worker's World," the museum's newest exhibit, offers a chance to regain some of the perspective you lost in a tantrum the other day when the Orange Line showed up late at Farragut West, God forbid, and you dubbed it another tough day.

Most folks walked to work in this "Worker's World"; the tough part of their day was the work they walked to (60 hours a week next to a hot, clanking, five-ton lathe, for instance). The exhibit's photo murals, documents and artifacts focus on the 19th- century industrial village and company town -- using, as principal examples, the black- powder mills begun in 1802 by E.I. du Pont on the banks of the Brandywine in Delaware and the steel mill opened in 1887 by the Pennsylvania Steel Co. at Sparrows Point outside Baltimore.

The exhibit's tin lunch pails, oak-and- brass pendulum timeclock and lifesize murals fit nicely at the realistically grubby museum, which itself has recreated a garment sweatshop, an early 20th-century machine shop and a print shop with foot- powered presses. And if someone's left the door open to the box-making plant (not a re-creation, but the real thing) next door, you might get a better idea of how things have, or haven't, changed. WORKER'S WORLD -- from The Hagley Museum, Wilmington, Delaware, at the Baltimore Museum of Industry, 1415 Key Highway, Baltimore. Open 10 to 5 Saturday, noon to 5 Sunday, weekdays by appointment. 301/727-4808.
