I'm firstly going to give you some background.
I work for a west coast USA startup that performed extremely well this year (it doubled the last year income record). I work remotely from Europe and I've been working there for a little more than one year.
I just finished my bi-yearly performance review, I think I "constantly met and exceded the expectations" but I don't have yet the results of it.
My manager told me he asked the management a raise of X, which is approx the 20% of my current salary. He said he wanted to give me that much because I had not an increase in salary in my past performance interview (because I did join just 4 months before it) and because I was a key piece to deliver a huge project the company worked on during the past two quarters.
The reply from the management was that they were willing to give me Y (6%), because considering the country where I live, I already earn much more than the average.
While this is true, they never mentioned any distinction in salary related to the country of residence of the employees when they hired me, nor during the whole year.
Also, I already earn way less than my colleagues that live in the states (at least 35% less).
My manager refused their offer and now is trying to negotiate to give me more.
The questions are:
Is it common to pay remote employees an amount correlated to the place where they live?
Should I accept the 6% of raise or this may sign the beginning of a future filled with very low raises because year after year I'll earn way more than "the average"?
(Bonus question) How can I help my manager to make him land a good deal for me ?
