An employment contract is one of the most consequential documents a startup will ever sign. Get it right and you protect your IP, preserve your ability to let people go, and set clear expectations. Get it wrong and you could face unenforceable restrictive covenants, wrongful termination claims, or a dispute over who owns the code your engineer wrote on a Sunday afternoon.
This guide covers what Illinois startups must include in employment contracts, what to avoid, and the unique compliance requirements that apply to Illinois employers.
What to Include in an Illinois Startup Employment Contract
1. At-Will Employment Statement
Illinois is an at-will employment state. Your contract should expressly state that employment is at-will—meaning either party can terminate the relationship at any time, for any lawful reason, with or without notice. This is important because courts can sometimes imply an employment contract or just-cause termination requirement from employee handbooks, oral representations, or other conduct.
2. IP Assignment and Work-for-Hire Clause
Every startup employment agreement must include a clear IP assignment: all intellectual property created by the employee in connection with their duties is assigned to the company. This covers code, designs, inventions, trade secrets, and any other work product.
Illinois caveat: Under 765 ILCS 1060/2 (the Illinois Employee Patent Act), you cannot require employees to assign inventions that are developed entirely on the employee’s own time without using company equipment, facilities, supplies, or trade secrets, and that don’t relate to the company’s business or result from the employee’s work. Any IP assignment clause must include the statutory carve-out language or it may be unenforceable.
3. Confidentiality / Non-Disclosure Obligations
Your agreement should define what constitutes confidential information broadly and require the employee to maintain confidentiality both during and after employment. Include provisions for returning confidential materials upon termination.
4. Compensation and Benefits
Specify salary or hourly rate, payment frequency, and any variable compensation (bonuses, commissions). If equity is part of compensation, reference the equity grant document—don’t put equity terms in the employment agreement itself, as they need to be in a separate equity award agreement.
5. Duties and Reporting Structure
Define the position, reporting relationship, and general duties. Avoid being so specific that routine business changes (title, reporting structure) constitute a breach. A general description of duties with flexibility language works better for startups.
6. Restrictive Covenants (If Used)
Illinois significantly restricted non-compete and non-solicit agreements through the 2022 amendments to the Illinois Freedom to Work Act. Key rules:
- Non-competes are unenforceable for employees earning less than $75,000/year (threshold increases to $80,000 by 2027)
- Non-solicitation of customers and co-workers is unenforceable for employees earning less than $45,000/year
- Illinois requires employers to advise employees in writing to consult an attorney before signing, and must provide 14 days to review
- Consideration must be “adequate”—continued employment alone may not be sufficient for existing employees
7. Dispute Resolution
Include a governing law clause (Illinois) and choose a dispute resolution mechanism: litigation in Cook County courts, or arbitration. If you include arbitration, consult with counsel about class action waiver enforceability under Illinois law.
What to Avoid in Illinois Employment Contracts
- Overbroad non-competes: Illinois courts will not “blue pencil” (judicially modify) unreasonable non-competes—they will void them entirely. Keep geographic scope, duration, and activity restrictions narrow and reasonable.
- Handbook incorporation: Don’t incorporate your employee handbook into the employment agreement by reference. Handbooks change; binding them into individual contracts creates risk.
- Indefinite employment promises: Language like “we look forward to a long relationship” or “your position is secure as long as you perform” can create implied just-cause termination obligations.
- Missing the IP carve-out: Omitting the Illinois Employee Patent Act carve-out language can render your IP assignment clause unenforceable for personal-time inventions.
FAQ: Employment Contracts for Illinois Startups
Do I need an employment contract for every employee?
Not legally—but you should have at minimum an offer letter and a separate IP/confidentiality agreement for every employee. Full employment agreements are especially important for senior hires, employees with access to trade secrets, and anyone receiving equity.
Can I use a template employment agreement?
With caution. Generic templates may not include Illinois-specific requirements (the IP assignment carve-out, the non-compete notice requirement, Illinois-specific wage payment provisions). Have an Illinois employment attorney review any template before using it.
