That reflects a broader trend. The National Center for Employee Ownership estimates that 9,225 companies were offering stock-option plans, stock bonus plans, and profit-sharing plans as of July, up from 7,600 in 1999.

Winning Workplaces is a nonprofit in Evanston, Ill., that helps small-business managers improve their communication skills to make workers more productive and happier.

It assembled a team of respected judges, who culled the 80 applicants by looking at factors such as employee satisfaction ratings and by interviewing workers. The result? Eighteen Best Bosses - 17 from commercial companies and one from a nonprofit.
