So here is some real-world anecdata from this current month: I have been interviewing in UK with smaller companies and one of the first questions has been what compensation I am seeking. I have been upfront about my preference (remote first) and travel costs, which I calculate as approximately the equivalent of £10k/year gross salary for each scheduled day/week on site from my location to nearest major city. I have said that I can do up to 2 x regular day/week onsite.

1. Nobody has disputed my reckoning or reasoning
2. Startup company advertised 'hybrid'. I gave a comp ask saying 'with 1 day/week on site'. They came back to suggest a 10k lesser figure full remote. I withdrew because I accepted another offer but this would have been acceptable.
3. Scale-up company- again advertised 'hybrid', suggesting 1 day/fortnight onsite. I gave same salary/travel calculation. They came back with offer of my basic figure for remote with quarterly visits at company expense instead, i.e. travel, accommodation etc. I accepted this.
