> When he raised these issues — first with Spirit management and then with Boeing’s ethics program — he was fired
Eh, at cursory glance it looks possible that Boeing has wrong doing. Perhaps we'll see an email come out of discovery from Boeing telling Spirit to solve the problem (of somebody raising complaints).
All he has to do is show Spirit retaliated and Boeing is immediately implicated. "Because Mr. Cuevas served as a contractor for Spirit and subcontractor for Boeing and was directly employed by Strom, the Companies are liable for his retaliatory discharge under AIR21."
The complaint is against Boeing (they're literally listed under the "v" section) so its completely reasonable for somebody to report these documents as a complain by a new whistleblower against boeing.
