Short work experience - omit?

Hi,

Would appreciate any advice as to how to approach the following scenario in my MBA applications.

I'm deliberating whether to include a short 1-2 months of work experience I had.

The thing is that I really wish not to have any background check companies or adcoms contact that company. Essentially I told the company that I wish to terminate my contract with them as the role was very far from the one described, and apparently, they took it really hard and started making some allegations about violations of company guidelines etc. (i.e., that company can screw me over if contacted).

Now, I know that an omission of information could be equivalent to lying/misrepresentation and could potentially serve as grounds for rescinding my offer (if admitted), but would really appreciate good thought advice as to how to approach this issue.

Most people suggest simply omitting this short work experience, as it is not material enough and as there is extremely low chance that any background check company can find out about it. Regardless, I'm worried about the possibility that it will somehow come up in the background checks (I'm based in central Europe, not in the US).
