Can a former employer restrict me from working in their building if they are the landlord?

Hi all,

I’m looking for some guidance on a situation involving my former employer (let’s call them FE) and my current employer (CE).

A few months ago, I was let go from FE without warning. They cited vague performance issues, but I was never provided documentation. I filed for unemployment, which they contested with three different reasons for my termination. Ultimately, unemployment was granted in my favor.

Fast forward — I’ve since been hired by CE, and things are going well. They is planning to move into new office space soon, and it turns out the space they selected is in a commercial building owned by FE.

My concern is this:

• The space CE is leasing is on an upper floor (4th), but I would have to pass through shared/common areas FE owns to access it.

• There was no legal action taken during my termination (no trespassing orders, no NDAs or non-competes), but the situation was unpleasant, and I’m worried FE could try to restrict my access or create friction once they realize I’m back in the building.

So my questions are:

1. Would it be wise to preemptively notify my employer’s HR team about the connection

2. Can FE, as the landlord, legally prevent me from being in the building or using shared areas if my current employer is a tenant?

3. Could they take any action to block me from working there or make things difficult for my new employer?

I want to be respectful of boundaries and avoid unnecessary drama, but I also want to understand my rights. Any advice would be appreciated. Location: Nebraska

Thanks in advance!
