The lobby of the Boston Harbor Hotel has Italian marble floors, elegant five-foot-tall arrangements of orchids and beach grass, and views of of luxury yachts and cruise ships docked outside. Amid all this opulence are black-and-white portraits of 21 employees, many of them immigrants, who have worked at the hotel since it opened 25 years ago: Beena Jaikaran in the laundry room, Carmen Dejesus in room service, Yok Lam from housekeeping.

The hotel is the highest-ranked medium company in this year’s Top Places to Work survey, and the respect management shows to its staff is a big reason the employees rave about working there.
