How much does the salary increase when the main engine factory switches to the parts factory?

The main engine factory jumped to the parts factory for a salary increase of 2000. OEM is the place where suppliers supply spare parts, only producing the main core technologies, and outsourcing other businesses to other companies. The parts factory is engaged in the manufacture of auto parts, foam plastics and plastic products. People in auto parts and main engine factories can do this job well by jumping to the parts factory, so it's no problem to raise their salary by 2000.
