Will demotion affect EB1B?

I messed up a bit at work so I'm getting a demotion soon. I'm still gonna be doing the same work, just lower pay and one-step lower rank. Luckily, company said they'll still do my EB1B. Is this going to affect my case though?

to Dolores:

I don’t think it’s going to affect your EB-1B case as long as your position is still a permanent one.

to Dolores:

Hey, demotion shouldn't affect your EB-1B case. I agree with the previous response, just make sure the position is still permanent.
