I resigned from a job that didn't reimburse mileage and required me to drive quite a bit. Great pay and flexibility there but with the tax changes it just didn't make sense. I tried to influence policy change around it unsuccessfully.
New job will be modest bike ride almost entirely on a bike path separated from the road 4-5 days a week. The days I will need to drive my mileage should be under 50 and there's a plan to get it under 25.
Giving up a little flexibility but I don't think it will matter as my schedule will now be more similar to my spouse and friends. Lower base salary but I successfully negotiated for compensation for some extra tasks and the option to take side work on my own! Should make for an income neutral change!
