a letter to my boss's boss!

so which is it? are you doing outside sales and thus getting cut out of the car allowance or is your boss forcing you to stay in the office all day, in which case you really don’t need the allowance? In the first paragraph quoted it sounds like you were hired on to do sales calls/visits but aren’t. Then in the second one it sounds like you are doing calls/visits and not being properly reimbursed.
