Opie,

As Check said, a thorough answer would be long but I'll take a shot at a shorter one.

A greenslip and an inverse assignment are basically the same for a line holder, double pay and no credit. (This is assuming no conflict with another trip on your line.) The difference comes in that a GS is voluntary and you have to submit a GS request to get it. The GS is assigned in senority order. After you get one, you go to the bottom of the list and others more junior to you get the opportunity to get a first one before they come back to you for a second one. An inverse assignment is just that, they start at the bottom of the list and go up to try and cover the trip.

A greenslip and inverse assignment on reserve pay single pay no credit and you get your violated reserve X days back. In other words, you get the pay for the trip above the reserve guarantee and your day off back. These payback day start approximately 9 hours after you block in from the trip. When manning is very short, if you are senior enough, this is a great way to fly a 75 hour month and get 145 hours of pay. Assignment of these works as described above.

This is a simple answer and does not take into consideration greenslip with conflict and inverse assignment with conflict. I haven't read "when scheduling calls" lately but I'll bet it has a good explanation and I'm sure you can download it from the Union website.
