Shouldn't the gov ban the practice of employers asking for payslips? With how the economy is now, fresh grads will get a low starting salary and other workers will experience a pay cut. When they move jobs, they'll forever be scarred by their lower pay due to COVID-19. Even promotions will be based on this cut pay.

In the U.S. this is already a thing to prevent employers from lowballing those who unfortunately had a low-paying job previously. There are other ways to verify employment and you should be paying a person for what they currently do, not what they were previously paid.
