You want to keep historical data, yes? Then perhaps...
tblEmployee (which also contains the supervisor and PM because they are employees) needs a supporting tblEmplSuper table with fields for employee id (not their name) and the employee id of the supervisor and likely a date field for when this association began. The form you use for training could be pulling in the super associated with the training at any given point in time. This could be a combo where the row source gets the super ID based on the Max of Date for that employee (if you're using a date field). That supervisor ID gets stored in your training table(s).
