Pros

Fewer Shifts than the typical 9 to 5.

Cons

Longer hours. 13 hour days, and 208 hours a month but only 16 shifts a month. Justifies above average salary range.

Pros

Great value proposition for clients.

Cons

In my experience, there can be situations where questionable behaviour is not addressed as strongly as expected, which may feel like having to overlook certain issues.
