Not OP, but i was in the exact same position as him. Doing the same job, but with pay discrepancy of RM2k.

We shared our salary info among ourselves. Which is why there are increasingly more companies that impose penalties on sharing salary information these days. Even my current company would impose S$200 for every infraction found.

Probably quite easy to narrow down the list when some disgruntled colleague takes it up to HR and ask why is the pay gap so huge.

EDIT:
And the RM2k gap is just the tip of the iceberg. As we found out together, we have the same number of years of experience, similar education, and even the same percentage of increment throughout the years since we started working. The only difference between us is our starting salaries upon graduation. And thus the pay gap snowballed to RM2k at the time we compared our salaries.
