If this is a tax issue, then we should be able to use reimbursable Ground Transportation to a location just off the airport (avoids the domicile).
I do not let the driver pick me up or drop me off at my residence. I have them pick me up across the street (curbside) to avoid the taxes. A short walk fixes that problem.
Use of ground transportation at/on/or near the domicile appears to be permitted in the contract for everyone. The problem is the Expense Reporting System does not have the fidelity to list pickup and drop-off locations inside a city radius. The domicile is the actual airport property - and I cannot find a restriction for a ride to or from the domicile. I would will gladly use my funds for a 1.5 hour ride to a position close to the airport (hotel or off airport lot for example) and I will get myself the short distance remaining for tax purposes.
I will address this with the union to see why some are being restricted from expensing a legit use of bank funds.
