Conducting internal investigations allows businesses to self-police, protect themselves from escalating matters to civil court, and promote a strong business culture. However, launching an internal investigation also opens the door to various risks, including claims of bias and discrimination.
An employer defense lawyer can promote fairness in your investigatory processes and safeguard your business from allegations of misconduct. Being proactive is the best approach, particularly for organizations that operate in litigious environments like California.
Here’s everything you need to know about how an employer defense lawyer can help conduct internal investigations.
Why Internal Investigations Are Critical for Employers
Internal investigations protect your organization when employee complaints arise. You must address allegations quickly, especially if they involve one or more of the following topics:
- Harassment
- Discrimination
- Retaliation
- Wage disputes
- Policy violations
Failure to investigate these matters properly can increase your legal exposure and damage workplace morale.
More than half of organizations experience an uptick in employee misconduct claims when undergoing major technological or structural change. If your business is preparing for an overhaul, proactively enlisting the services of an employer defense lawyer can prepare you for a potential rise in internal investigations.
While many investigations are led internally by HR, legal oversight can help ensure that your process can withstand scrutiny if litigation occurs.
When Employers Should Initiate an Internal Investigation
Employers should launch an investigation whenever credible complaints or potential violations arise. For example, if you receive a formal complaint, an anonymous report, or concerns via your chain of command, it’s wise to address them in a timely manner.
The following should automatically trigger an investigation:
- Complaints of harassment or discrimination
- Allegations of retaliation
- Workplace misconduct
- Wage and hour violations
- Concerns of ethics or compliance issues
When you respond swiftly, it shows employees that you take their experiences seriously and are committed to maintaining a fair workplace. If you aren’t sure whether an investigation is warranted, consult an employer defense attorney.
The Role of an Employer Defense Lawyer in Workplace Investigations
An employer defense attorney can not only help you determine when investigations are necessary but also provide valuable structure and legal oversight throughout the investigation process itself. In this way, working with an experienced lawyer keeps your investigations fair and defensible.
Your legal counsel can assist you with:
- Outlining the scope of your investigation
- Advising on your legal obligations
- Scheduling interviews and preparing documents
- Evaluating potential liability
- Preserving attorney-client privilege
By handling an investigation properly, you can address issues internally while minimizing the risk of escalation. If an employee files a lawsuit, your lawyer will make it a priority to manage the investigation in a way that protects your interests.
Protecting Attorney-Client Privilege During Investigations
One key advantage of involving an employer defense lawyer is the ability to maintain attorney-client privilege in certain circumstances.
If your legal counsel directs the investigation, communications and findings may be protected from disclosure during litigation. As a result, your organization can candidly evaluate risks and make informed decisions.
This protection can be especially valuable when your HR team is dealing with sensitive or high-risk allegations. They can discuss their concerns with a knowledgeable legal professional while enjoying the benefits of privileged communication.
Conducting Fair and Thorough Employee Interviews
Interviews are one of the most important elements of an internal investigation. However, if they’re mishandled, the information you gather may not be admissible in court.
Your employer defense lawyer can help your HR team structure interviews in a way that’s both effective and legally compliant, offering guidance on how to:
- Ask appropriate questions
- Avoid leading or biased language
- Maintain confidentiality
- Document responses accurately
Well-conducted interviews are more likely to yield useful evidence that you can incorporate into your decision-making process. That’s particularly important if the interviews will be used to make disciplinary decisions, such as suspending or terminating an employee.
Complying With California Employment Laws
California has some of the most stringent employment laws in the country. As an employer, your organization must adhere to strict obligations when handling workplace complaints and allegations of misconduct. In some situations, you may be legally required to launch an investigation.
An attorney will understand the regulatory burden placed on your business and help you conduct compliant investigations in accordance with state laws. Obtaining legal oversight also reduces the risk of procedural mistakes that plaintiffs’ attorneys might later use to challenge your investigation.
Documenting Investigation Findings Properly
How you document an investigation is as important as how you conduct it. Investigators should maintain detailed records of the initial complaint, interviews, and any evidence they gather during the process.
Unfortunately, these processes aren’t in the wheelhouse of many HR professionals.
An employer defense lawyer can help your human resources department address these elements of the investigation in a way that guarantees compliance. Proper documentation will also strengthen your defensive posture if the dispute escalates into litigation.
Avoiding Common Mistakes During Internal Investigations
Even well-intentioned investigations can create legal risks if they’re managed incorrectly. Here are a few mistakes you should avoid:
- Failing to respond to complaints in a timely manner
- Not interviewing key witnesses
- Demonstrating bias during investigations
- Inadequately documenting your findings
- Committing breaches of confidentiality
Any gaps in your investigatory process can drastically increase your liability.
How Legal Guidance Strengthens HR Decision-Making
Once you’ve completed the investigation, it’s time to make a decision. You may need to discipline one or more employees, make targeted policy changes, or offer training to correct deficiencies in company culture.
Seeking legal guidance beforehand can help you evaluate the implications of different decisions. Your attorney’s insight will allow you to address workplace issues proactively while protecting the company’s interests.
Partnering With Experienced Employment Litigation and Defense Counsel Firm
Internal investigations must be approached delicately. Otherwise, you risk the matter escalating to a civil suit, which can have severe public relations and financial implications. Enlisting the aid of an employer defense lawyer is one of the most effective ways of protecting your business and promoting integrity during internal investigations.
When searching for lawyers to represent you, prioritize legal professionals who have experience with California employer defense matters. That’s the best way to effectively safeguard your organization and its reputation.
