As noted by, @ebh+1co794vH. The most recent DS&C Townhall touched on all things salary in the SF Bay Area. Yet, no real good answers other than, CVX does benchmarking against industry peers (oil/gas), not necessarily based on the area. Benchmarking only counts so much when your base salary/401k/benefits is already below other industries in a specific area. Lets be real...even govt employees get paid more than large number of CVX employees. Take a look at transparentcalifornia for those wondering.
While, benchmarking against peers is great, how about peers or industries in the areas/locations you operate. Lets take a closer look....not many oil/gas companies want to operate, if at all, in the area or state as a whole. Phillips Rodeo going to bio, Marathon Martinez being scaled back and layoff events in 2020, Valero Benicia days are numbered. New air requirements coming down the chain requiring large amounts of process/emission control equipment changes....
If I was in IT, and in SF Bay area, I am not working for CVX....where does my growth go. IT, SF Bay Area...you are going to South Bay or hoping to hit the IPO lottery in a start-up.
Then again, if you are CVX, in SF Bay Area, you should already be looking for your next role.
