10% pay raise, but all of your work product is destroyed. (No loopholes)

10% pay raise including base pay, bonuses, tips, etc.

You keep your same job, work functions, and career path but all of your work product is destroyed. If you're making food or a product, as soon as you're done it all goes into the trash. If you're cleaning or doing a service, somebody comes around and undoes the work right after. If you're in sales, all of the sales are canceled (but you still get commission), etc. if you're a therapist, either the patient instantly forgets everything you said completely, or an anti-therapist comes in and exactly offsets every word you said. If you are on a construction crew, somebody follows behind and undoes your work as you complete it. Etc etc.

You are held to the same performance standards as before. Work that would have gotten you fired or demoted will still get you fired or demoted. Essentially, you are treated as an employee as if the undoing part didn't happen, you just know that your work has been meaningless outside of what you get paid.
