Thank you for “cutting and pasting” and providing a link, nsr.
From what I can tell, the difference between the max salary and the amount paid would include overtime, additional duties, etc. Still, the biggest difference here was ONE person (out of 188) who made $141,665, which was 90% more than base pay, not 100%. That was a definite outlier, and I don’t know what the story would be behind that number. Most of those employees made about 20-30% above base if they worked much overtime, not 50%-100% of base.
Here’s just one sample (taken directly from the series, not edited). This one shows them averaging about 16% of base.
The reason for the O/T is because they have to fill every position every day, it’s not because of 24-hour shifts. This type of shift is actually less expensive for employers because they need fewer people (and fewer pensions, healthcare benefits, lower recruitment and training expenses, etc.) than if they were to have 8-hour shifts.
