Re: Not worth it ...
Depends.
(circumstances, reasons, country you work in)
It would count as a business trip, so any costs should be paid by the employer (some exceptions, like daily rates for food).
Tax-wise the actual costs could also be claimed, since it was a business trip, not for leisure.
If it was a regular occurrence, a commute, it depends on the feasibility of the alternative modes of transport. And the special circumstances. Might be a longer battle, though,until they accept the claim.
