The finance manager at my job mistakenly sent an excel file (with everyone’s salary) to a public work group… now I want to leave

Picture this, a random afternoon at work. Most communication channels are crickets and you get a random notification. It’s from the finance manager… hmm what could this be? I download the file and the shock of my life. I can see everyone’s salary including increases over the years. Several people making 2 - 5x my salary and getting 30% raises regularly! I was beyond shocked and I froze for almost one hour. When I asked for a raise I got a silly 4% yet several people got above 15%. I literally built fundamental tools for this organization and I’m generally a high performer. I haven’t been able to get over it and I feel disgusted since waking up daily to working with inefficient people making 3x my pay. I’m putting this on the internet so I can look back when this situation has turned around and I get to work with a fair employer or become one. \#disgusted
