" 1035 APPROPRIATE ACTION FOR FAILURE TO FOLLOW THESE REGULATIONS
A command/unit is expected to take appropriate disciplinary action when a traveler and/or AO fail to follow these Regulations. Disciplinary action should be for willful violations and may be in the form of counseling (oral/written), non-judicial action, or other appropriate personnel means. Disciplinary action must not be through refusal to reimburse unless no authority exists or is so stated in this regulation."
1. Is your CC REALLY going to give you counseling, NJP, etc. because you didn't use your GTC, or booked your airfare through delta.com instead of DTS (especially when the ticket price is < the govt constructed cost for the city-pair), etc? I'd wager not in all but the most bizarre cases. I could see those types of things if someone was defrauding the government by submitting doctored receipts, loading cinder blocks in their trailer for a DITY, etc. But we're not talking about obviously bad stuff like that, we're talking about you getting reimbursed for airfare you bought to go on a TDY you were given a couple day's notice on right before a weekend (no time for the standard DTS timeline).
2. If GS-15 d-bag is the ultimate AO holding the key to your unit's LOA, then shouldn't he be the guy approving DTS? Sounds like you're saying TSgt Smith is an AO, approves your DTS, but because "god" didn't know about it, he won't reimburse. So I think you have two COAs...
COA 1: Shove 1035 in his face and say no JTR portion was violated and you had authorization/orders (notice there is no where in the JTR that says there is rank among AOs...though FM can trump an AO, but he's not FM, so his argument is DOA).
COA 2: Don't write bullshit emails, just use DTS normally and refuse to go on anymore TDYs until your GTC is paid per the JTR (hypothetically saying this happens again). Saw a bro who was fighting the finance reimburse GTC battle, he said fuck it, he's not going on any more TDYs until it's fixed (and this is a guy who has a lot of necessary TDYs for his job). He missed a couple big TDYs, nobody could officially fault him, problem was solved shortly after.
I personally like the idea of simultaneously executing both COAs.
