'The level of that cadet salary likely reflecting the method of "repayment"'
Correct me if i'm wrong but I believe it just so happens that the cadet salary at ezy just so happens to be 12k less than a normal (d/e) one ? totally reflecting a £1,000 a month "repayment".
I agree in that it's best not to see this as a reimbursement as such but rather just a part of your salary.
