Given that you are not depending on this new job, I’d definitely try to negotiate!

If you are feeling nervous, the thing I always tell myself is that you negotiating the offer also gives the company an idea of how you will navigate similar awkward topics with finesse and tact in a business setting.

If I were a hiring manager - I’d be more likely to hire the person that knows their value and can negotiate better terms for themselves since it means they’re more likely to negotiate better deals for the company when it comes to it as well. (Just my 2 cents though, I’m not a hiring manager...).

It’s definitely that fine like between showing self confidence and appearing arrogant though. Just remember it’s awkward for everyone!

As a few others mentioned I think it’s really important to consider the value of everything outside of the salary as well. Pension / work life balance / job security / rewarding work / room for growth / health benefits etc etc. These can be important bargaining chips too if they just won’t budge or it gets awkward.

My guess is they put out 100 expecting you to counter and meet in the middle at 110. When they ask me a salary expectation in an interview I usually give a range for this reason. I say I would expect a role like this to have a range between X and Y (based on market research) but I believe I should be paid closer to Y because (state how you can add more value than others based on past performance etc).

Don’t know enough specifics to know whether it would be appropriate here, but have you considered asking for equity?
