Difference between 'Not being releaved' and 'Not getting releaved'

[EngLearner]

Hi All,

I want to tell someone that Mrs. XYZ is not getting releaved from job before christmas but only after a week of christmas. Can I use the below sentence?

Mrs. XYZ is not being releaved before christmas but only after a week of christmas.

What does these sentences mean?

Mrs. XYZ is not getting releaved before christmas but only after a week of christmas.
The company is releaving Mrs. XYZ before christmas but only after a week of christmas.

Is there any other good way to tell this?

Thanks,
EngLearner.

PS: Please correct the mistakes, if any, in my post.

If you mean 'relieve' in the sense of 'dismiss' (usually because the person concerned has done something wrong), this is how I would say it:

Mrs XYZ is not being relieved of her duties before Christmas, but only a week after Christmas.

Hi Conchita,

I mean the same with relieve.

What do the other sentences mean? Are they completely ungramatical?
