I left my job less than a year ago due to personal reasons. I reapplied and was hired for the same position but I’ll be making $5 more an hour

I'm not sure if this belongs here but I'm honestly stunned at such a huge increase in less than a year. I am almost certain that the people still working the same position aren't getting a $5 raise. Even though it wasn't intentional, I see now that it literally pays to job hop, sometimes.
