And if they are all coming below you in your base it is making more pairings available for your bidding with more pilots junior to you as well.

They will come in below the most junior in base pilot. How is it making more pairings available to bid? I foresee just the opposite. IMO the company will invoke TDY when they anticipate handing out a lot of green slips in a category thereby reducing green slips. With TDY they can adjust a category on a monthly basis. Heck, they could just grow ATL and TDY to category's they need too.

An alternative is to just build pairings that go through your base instead of originating there. So you still don't get the flying. With TDY and the TDY pilots going to the bottom of the list you'd end up with a better schedule than with flights not being available for your bid at all.

See above. You seem to think TDY pilots coming in base means more time in base. I don't.

It sounds like your biggest concern would be alleviated simply by restricting the amount of time that a TDY could be conducted, such as a maximum of 3 months.

Having worked somewhere previously that allowed TDY, it's not used how you seem to think.
