The application requires us to submit a letter which specifies duties, positions held over the period of work ex, annual salary etc. This letter has to be signed by the supervisor but I had mutiple bosses over my 6 years of experience so do I need to get letters from everyone of them or just getting it from the most current supervisor suffice?
Does it have to specifically state the salary because again my most current supervisor wouldnt have knowledge of the salary I was drawing over my entire work ex.?
