This is the 4th one I've seen, All with a different breakdown.
So $4.55 x 2 passengers x 7 days x 20 cabins x 52 weeks = an annual salary of $66,248.
$4.55 x 2 passengers x 7 days x 25 cabins x 52 weeks = an annual salary of $82,810.
Plus additional cash gratuity of $20/cabin (20) /week + $20,800
Plus additional cash gratuity of $50/cabin (20) /week + $52,000 + $82,810 = $134,810
Tell me again that they are underpaid.
