Based upon the recruiters messaging me, if I gave up my remote job for one that required in-office attendance I would get an immediate 30% pay bump.

That would however, demand an hour and half commute each way and that would impact my ability to take my children to school and be involved with family meals. Back when I did have a hour commute each way it was costing me £2,800 a year in fuel, plus £2,220 in parking fees, plus about the same again for lunch out with colleagues.

So yeah, i'd get a 30-40% pay bump, but a large percentage would be consumed by additional costs with no benefit to my performance.
