I work for a company that has 3 offices/sites.
I theoretically work at office A (although haven't been in for 2 years as it's been closed due to covid). I live 20 minutes away from office A.
I work remotely and occasionally do trips to offices B & C when needed. My expenses (fuel - plus hotel if staying overnight at site C) are paid by the company.
We're starting to go back into the office now and I have agreed to do 1-2 days per week at office B. Office B is 40 miles away, on very busy roads. It takes 90 minutes to get there. So a day trip will involve 3 hour commute and an 80 mile round trip.
Manager has suggested that we change my usual place of work to office B, so that the company don't have to pay me fuel expenses or give me time off in lieu for my longer commute. I don't want this and have said that I would not have taken a job 40 miles away, especially as it means a 90 minute commute each way.
Lots of other people work across the three offices but no one else in my team has had this suggested to them.
Am I unreasonable to refuse this move?
It wouldn't be feasible for me to move closer due to kids schools/activities & OH's job (which is 20 miles in the opposite direction).
