Hey, I didn't say an employee should pay for business fuel in a company car! .... An example .. I worked for a large company .. had a company car ... all fuel was paid ... where "all" = business + private. Then one day, the company changed the fuel policy .. they were willing to pay for business related fuel only. All private fuel was to be self funded. Why? Times were tough .. early 2000's .. post dotcom ... companies looking to save from anywhere and everywhere ... so, like all employees, I swallowed the new rules, but still had a job, paid the mortgage, put food on the table .. And yes, you could argue the new rules created a larger management overhead, with some complex system to define what's business and what's private travel ... but it's irrelevant ... as an employee, that was the new policy, implemented immediately. This was when I worked in the UK. No unions involved.
