I propose that the reimbursement of commuting costs be regulated in a fair and transparent way that will also help to save money.
A practical example:
Two colleagues: 1. 30 km away from the workplace, 2. 12 km away from the workplace. Both commute by private transport. The first one is entitled to a mileage allowance due to current legislation or rules, the second one to the cost of public transport. The mileage allowance is calculated according to the actual working days. Public transport costs are reimbursed for the whole month if the worker is on duty at least 10 days a month.
Both staff members were on duty for 10 days in August.
Reimbursement: 1st colleague: 60 km x 10 days x 8% of the petrol price... = approx. € 72
2nd colleague: monthly ticket (once on public transport) = 82.8+97.20= 180 €
 
Proposal: Commuting costs should be calculated on a per kilometre basis for all, but in order not to penalise the minority who actually use public transport, they should be charged on the basis of the invoice submitted for the purchase of the monthly pass or the invoices for the purchase of individual passes.
This will actually save some money, it will do away with the very 'ridiculous' legislation, and there will be less administration!
