While defending my salary raise, my girlfriend intervened; was she right?

I think you have a point: if the workload and performance are increasing, that should reflect in the raises. I don't understand why your partner is being demotivating about this matter. Instead of thinking about losing their job, they should be supportive of your success.

Honestly, your partner might have been a bit reasonable. Asking for a raise during tough times when finding a job is difficult is indeed a risky move. Maybe if your approach or the way you expressed your request for a raise seemed too bold, they felt the need to caution you. There's no need to assume bad intentions.

Support is very important in personal relationships, but professional matters like work should not be mixed with private life. Perhaps your partner is worried about you thinking of your well-being, but this is entirely your domain. If you're hesitant to advocate for such raises in a job interview, maybe you can seek guidance from a career counselor.

I forgot to add this: I have already expressed my salary request quite calmly and with justification. In fact, such things are being discussed at work, and there are those who have received raises. My partner probably didn't understand the seriousness of the situation or exaggerated it too much. I wrote this out of disappointment, not anger.

Asking for a raise is quite natural based on your workload and performance. But it's important not to turn this into a conflict with your partner. Maybe you can sit down and have an open conversation like, 'This is about my career and the dynamics at work.' That way, they'll understand your intentions better.
