Accepted a job offer right before a company wide inflation raise

Hey all,

I'm graduating this December and have recently accepted a job offer for a company making 73k. I know 4 others that have also accepted an offer all for the same amount.

I just recently found out from someone who already works there that there was a company wide inflation raise of 10%

Today I heard from two students who were just offered positions for 80k

What's my best course of action for something like this?

Edit:

Found this on their website

> XXX will not discharge or in any other manner discriminate against employees or applicants because they have inquired about, discussed, or disclosed their own pay or the pay of another employee or applicant. "

Edit 2:

All of us are graduating at the same time, from the same school, with the same degree
