Alright I did some research and would like to close the loop on this.
FM-1 is fairly vague on bidding and military leave, the Pilot Contract (Rev 13) is a bit clearer.
For specific language look Sec 11, Page 2, C-5. It's electronic page 108.
In summary - if you're on "authorized leave" (this includes military leave) during got bidding process you may request a bid packet "at your own expense" (they are electronic now so this is a legacy comment) and submit that bid "in writing" (legacy comment - use email folks).
You can then contact the Chief Pilot or his designee and provide them with a bid list of what they want. The CP must submit this bid on their behalf as long a they are "reasonably assured" the pilot is returning to work on the FIRST of the following month.
Okay so here's what I would recommend someone do . . .
1 - avoid mil leave between 15-20 of any month so you can control your bid completely. If your required to make military leave during these days submit a bid as your normally do (using the App probably) - email the Chief Pilots office with the EXACT SAME bid data, then call and ask it the call be recorded confirming that they have your bid and they will submit it on your behalf.
2 - Avoid mil leave on the first of any month. If your commander has you take any, post it to the company after you've been awarded a bid.
3 - The company is honestly really good with us military guys. Make sure we maintain a positive relationship! Be an honest broker with Envoy on your military leave, and with your commander on your availability. Remember the Army/Air Force/USMC will always ask more of you - but unless you are non-voluntary activated you can say no. If you say yes, you're allowed to under USERRA.
4 - In either case, take care of yourself! Don't string yourself too thin between the military, the airlines, and your family. I've been told you can only successfully win at two. I would argue that as long as you manage expectations and work load by saying "no" to your reserve job and the airlines you can have a successfully family life.
5 - Again, no ill will with the company. I think they're trying to do their very best. Remember they deal with "problems" all day long - so help provide them with solutions.
Thanks fellow vets!
