Colgan has ready reserve
8 hour shifts and three per day of AM, PM and overnight
Shifts can be extended (I did a 12 two weeks ago)
Paid at 4 hours
With no contract you could sit hot reserve 5 days per week for the entire month.
You can sit hot reserve until 2200 and then start hot reserve again at 0600 the next morning. I consider this to be a potential plus. If you are working the 0400 reserve then your first day is non commutable. If they switch you half way through to an evening reserve and keep it that way you then will finish at 2200 and be non commutable on both ends.
