I know a lot of people here encourage people to speak about pay with their coworkers, as keeping it secret only helps the boss. There are a few issues with this:
- There is no reason to think your coworkers won't resent them for making more money.
- Your coworkers may start asking you for money if they know you make more.
- They can use it against you.
In general, I try to hide as much of my personal life as possible from my coworkers. Sharing information can put one in a vulnerable position.
