"Most of our ships are no longer serving guests. As a resulted, we must now shift to a staffing and compensation model for April, May, and June that balances the current economic and operation situation with the needs of our shipboard team members," said Susan Coskey, the senior vice president of human resources for Holland America Group, which includes Holland America Line, Princess Cruises, Seabourn, and P&O Australia. All Holland America Group crew members have continued to be paid since the group's parent company, Carnival Corp., halted operations in March, Coskey said in the letter.
