Edited to add link to story I'm quoting.
Hyatt Hotels Corp. laid off the entire housekeeping staffs at the Hyatt Regency Boston, Hyatt Regency Cambridge, and Hyatt Harborside Hotel after the morning shift had ended on Aug. 31, citing challenging economic conditions, and immediately replaced them with workers from an out-of-state staffing firm. The housekeepers had been training those very workers, from Georgia’s Hospitality Staffing Solutions, who they were told would be filling in for vacations.
Now, why would they make a move like that?
