When someone files an unfair labor practice (ULP) charge, employers must act fast. The National Labor Relations Board (NLRB) enforces these rules, and meeting its deadlines protects your right to tell your side of the story. Understanding California law helps you respond correctly and on time after a charge is filed.
What happens after a charge is filed
When the NLRB receives a ULP charge, the Regional Office sends a copy to the employer. The assigned investigator may request documents, emails, or witness statements. There is no fixed national deadline for this initial response, but the investigator usually gives several days to two weeks to submit the requested information. The timing depends on the case’s complexity and the agency’s workload.
Responding to a complaint
If the investigation shows enough evidence to move forward, the NLRB issues a formal complaint. At that point, the employer must file a written answer within 14 days. The response should directly respond to each allegation. Failing to do this in time allows the NLRB to treat the claims as admitted, which can quickly lead to an unfavorable decision.
Why quick responses matter
Fast, organized cooperation helps employers demonstrate good faith. Keeping updated records of workplace policies, disciplinary actions, and communications makes it easier to answer questions and meet deadlines. The sooner you provide information, the more likely investigators can fully understand the facts before deciding whether to proceed.
Staying organized helps your defense
Good record keeping and timely communication often make the biggest difference. When you respond quickly and clearly to an unfair labor practice charge, you protect your company’s position and show respect for the process. Every day counts once the NLRB sends a charge notice or a complaint.
