Business partner disputes are one of the most common reasons companies end up in litigation. They are also one of the most preventable.

The phone call usually starts the same way. Two or three people built a business together. Things were good for a while. Then one partner wants to leave, or wants the other one out, or stops showing up, or starts taking money they are not entitled to, or quietly starts a competing business on the side. And when the moment of crisis arrives, everyone reaches for the operating agreement.

What they find there determines almost everything about what happens next.

Most business disputes do not start with bad intentions. They start with contracts that were written for a business environment that no longer exists.

The vendor agreement you drafted three years ago did not account for tariffs reshuffling your supply chain. The independent contractor arrangements your company relies on were built before enforcement agencies started looking much harder at how businesses classify workers. The employment practices you put in place assumed a set of rules that several states, including Illinois, have now rewritten.

In 2026, the distance between what your legal documents say and what the law now requires has grown wider, faster, than most business owners have had time to notice. That gap is where disputes begin, audits are triggered, and litigation gets filed.

If your company uses software to screen resumes, score job applicants, schedule interviews, evaluate performance, or decide who gets promoted, you may already be violating Illinois law.

That is not a hypothetical. It is the current legal reality for employers operating in Illinois as of January 1, 2026.

A lot of business owners in the Chicago area know AI tools are somewhere in their hiring process. What most do not know is that Illinois now treats the misuse of those tools as a civil rights violation, with penalties that can reach $70,000 per violation, plus actual damages and attorneys’ fees. And critically, intent does not matter. If your AI produces a discriminatory outcome, you are liable whether you meant for that to happen or not.
