We all travel in our work, and often we claim money back from our employer. There is normally a set policy that states how much we can claim per mile/km, and sometimes this is based on a national framework.
E.g. for the UK there is a national guideline, and universities publish their own expense policies in the public domain (see attached sample).
What is your national framework?
What is your institutional policy for reimbursement?
