Sim Instructors, Sim Check Airmen, and Line Check all stay on the seniority list, and are marked no bids for “Training” for those specific months, they can go back to the line any month they want. Our jobs as line pilots on the seniority list are protected and represented by the union, however there is no language for us regarding compensation regarding training duties, in the sim or on line performing OE or line checks. That said we have very good people in charge of sim checks and standards so it’s not one of those places you don’t want to be. However, collectively negotiating our rates isn’t something that the union handles; quite honestly it needs to.
