When you are buying a mid-market company, the first 90 days after closing are critical for creating value. Investment plans often depend on finding operational synergies, which can mean restructuring and reducing staff. However, if the business has a footprint in California, an aggressive integration plan can trigger serious liabilities before the company is fully stable.
The state has its own Worker Adjustment and Retraining Notification (WARN) statute that applies to deals not covered by the federal law. Understanding California’s mini-WARN rule, or Cal-WARN, is key to protecting your fund’s return on investment.
State WARN vs. federal WARN
California’s rules are broader than the federal WARN Act, so they can apply to mid-market companies. These include establishments with 75 or more total employees (including part-time) over the trailing 12 months.
Federally, a mass layoff generally requires letting go of 500 or more workers, or at least 50 employees if they constitute one-third of the workforce. Under Cal-WARN, there is no percentage threshold. The law is triggered the moment 50 or more employees are laid off within any 30-day period.
Requirements for advanced notice
If your restructuring plan affects more than 50 employees, California law requires 60 days’ written notice to the affected workers, the California Employment Development Department (EDD) and local workforce officials.
Fulfilling this requirement demands careful planning due to statutory changes under Senate Bill 617. Under these rules, a standard termination letter is not enough. Cal-WARN notices must include:
- Company plans for whether they will coordinate transition services or not
- Contact information for the employer and the local board, plus career center information
- CalFresh food assistance details, including links and helpline numbers
If the company plans to work with the local board, those arrangements must be finalized within 30 days of sending the notice.
Financial implications of noncompliance
As the sponsor, you generally cannot approach workforce integration in California with the intent of fixing things later. The state treats Cal-WARN compliance strictly, that even honest mistakes can create liability.
Failing to follow the timeline correctly can cause the company you bought to pay damages to the affected workers, including:
- Up to 60 days of back pay and benefits for each employee
- Medical expenses that would have been covered under the company’s health plan
In addition to these payments, the state enforces civil penalties of $500 per day for each violation.
What private equity sponsors can do
To avoid employee-related liability and protect your returns, you can implement the following measures during the deal process:
- Check headcounts early to identify potentially affected workers
- Build in a 60-day waiting period if post-closing layoffs are necessary
You can also review the integration plan together with your legal counsel before closing.
Safeguarding your investment
A single misstep in a restructuring timeline can wipe out your projected gains through statutory fines and back-pay remedies. By being proactive about legal compliance, you can mitigate risks while protecting your deal from unnecessary exposure.
