Sort of been waiting for clarification/conformation of new starter FO on this thread.
I think we are saying....
Years 1-3 with Rishworth on contract to Norwegian ? Figures in NOK on PPJN apply.
Year 3 onwards with OSM. Better figures (again on PPJN in Euro and NOK) but still no direct contract with Norwegian.
So never any direct relationship with your actual employer.
The question I have, and I still believe it perfectly reasonable to ask and yet I cannot see it has ever been answered, is if Norwegian take a dislike to you (wear your hat incorrectly, upset a management type, are late to report a couple of times) and they "return" you to Rishworth/OSM, what happens and what recourse do you have under UK employment law?
As far as I can see you are then left in "dispute" with an agency with absolutely no chance of satisfactory resolution. My understanding of agency contracts is that the ultimate employer can return individuals to the agency for any reason they choose and do not have to justify why they no longer want an individual on their flight decks.
And do Rishworth pay UK taxes and National Insurance on behalf of the agency pilots they place with Norwegian or are they self employed?
