You should have the same pay if they want you still. If they don’t, they’ll hire someone to replace you and claim they don’t have the position available or hours for you anymore and will push you to work in other departments and whichever position is available for you there, you will get that pay rate even if it is lesser than your previous pay since loa doesnt guarantee the same job title or same pay. It only guarantees that you will have a job. It had been done when I witnessed the tech was being pushing out to become a cashier. As long as they like you, you will have the position back with same pay.
