Re: US IRS
Not correct. The (US) IRS are specializing in US pilots at ME airlines. We are a soft target and the same tactics used on pilot A can be used on pilot B as our compensation packages are standardized.
I know of three pilots who have received such letters and they probably know of three more each.
These letters are classic shakedown policies, they shake the tree and see what falls out. They only problem for us is that they see a forest of several hundred trees all nicely lined up in a row (a seniority list) and they will shake what ever tree they want.
The production line system worked for Henry Ford and now the IRS is making it work for them.
