I am currently working in the IT industry holding a blue card and after one and a half year, I received a promotion, which also included a salary raise.
I got to know about this promotion via e-mail in January.
January and February paychecks reflected already the new salary base, however, in March they decided I would need to sign an appendix to my contract in order to validate my promotion.
I did not accept the new job description, as they were mandating me to perform tasks way outside my scope of work.
In the March paycheck, I saw they rolled back my salary retroactively. Hence, I received a very low income, as both January and February gains were discounted in the March paycheck.
I am wondering is this is valid or against the laws? Also, did anyone already face a similar situation?

which is not relative to the question as this is a problem even a German citizen might face. So how is this related anyway to being an expat?
