Honestly, a much much higher salary. There are lots of things I’m going to have to deal with if I were to go back to the office; namely heavy traffic, transportation expenses, added stress, clothes (I mean, I’d have to use office-appropriate clothes whereas nowadays I have to be presentable only when I have meetings), food, waking up and preparing earlier than usual (sometimes up to 3 hours earlier!) and getting home late which gives me less free time, etc.
They’re going to have to offer a really lucrative salary for me to even consider returning to the office.
