As Summer Wears On, So Does Caterpillar Workers' Joliet Strike

It's been a long, hot summer for many working Americans, but perhaps none more so than the nearly 800 unionized employees at Caterpillar in Joliet, Ill., who have been walking the picket line in near-triple-digit heat on some days for nearly three months.

Despite the oppressive temps, picketing workers remain steadfast in their demand that Caterpillar Inc., the maker of large construction and mining equipment, share in some of the massive wealth it's accumulated by providing workers better wages and benefits -- and not freeze or cut them.
