Similar to what DrParasite has to say.
My company officers 3 pay rates: 8/10, 12, and 24/48. The hourly rate goes down the longer your shift. This is to keep everyone balance on an annual basis.
The benefit, is that the longer your shift, the more days off you have, which allows for more OT. Unlike the Doc, when you pickup a shift, you earn the pay rate for that length of shift, so if I pick up an 8 hour, I earn the lucrative 8 hour pay.
If you work a 48H shift where I work, you have 8 consecutive days off every 3 weeks. This allows for a massive amount of overtime. I make nearly double my base annual salary by picking up OT on my 48H schedule
