Sounds a bit shit.

If you can find a better work environment then quit. I wouldn't work weekends without some form of recognition, which is sounds like you are not getting.

I mean, why would you give 80% of a company a raise and not this guy? Sounds like maybe he isn't someone they want to keep around long term?

Indeed, it sounds like they want him to leave and if he isn't getting on with the other engineers it might be for the best for everyone.
