Should small businesses let employees use sick leave for mental health?

“I’m taking today and tomorrow to focus on my mental health. Hopefully, I’ll be back next week refreshed and back to 100%.”

Madalyn Parker, a web developer at the small software company Olark, emailed her team one day.

The CEO responded supportively, saying, “I just wanted to personally thank you for sending emails like this. Every time you do, I use it as a reminder of the importance of using sick days for mental health.” 

Until recently, mental health was considered a personal issue, not something employers needed to address. Today, that’s changed. Employees increasingly expect their workplaces to support mental well-being, not just physical health.

When Parker shared this exchange publicly, it was greatly appreciated and highlighted how meaningful it can be when employers acknowledge mental health as a valid reason for time off.

One of the simplest, most practical ways to support your team, without overhauling your entire benefits package, is to allow employees to use their existing sick leave for mental health days.

But how does that actually work? What’s the legal and payroll impact? And how can you offer this without creating policy confusion or risking compliance issues?

Let’s break it all down from a small business owner’s point of view.

Mental health days: What are they?

A mental health day is when an employee takes time off specifically to rest, reset, or manage stress, anxiety, or other psychological strain, without needing to justify it with a physical illness. It doesn’t require a diagnosis or doctor’s note but that doesn’t mean it’s vacation time. It’s simply using existing sick leave for mental well-being.

For small business owners, the question isn’t just what a mental health day is: it’s whether your current sick leave policy allows for it. In most states, if you offer paid sick leave, there’s no legal reason you can’t include mental health as a valid reason to use it.

In fact, some state laws already expect you to. For example, under California’s Healthy Workplaces, Healthy Families Act, employees can use paid sick leave for mental or physical illness, including preventive care. This leave can be used for attending therapy or counseling sessions, recovering from burnout or stress, or even supporting a family member dealing with mental health issues.

Even in states without specific guidance, expanding sick leave to include mental health is low-lift and shows employees that their well-being matters beyond the physical.

Now, what does this mean for your business if you don’t already have these guidelines in place? You don’t need to add new benefits. All you need to do is clarify how existing ones can be used and ensuring your policies reflect your workers feel cared for. 

What are the legal and HR considerations?

There’s no federal law requiring private employers to have a paid sick leave policy. But if your business provides it, whether by choice or because your state mandates it, you need to know how mental health fits into that policy.

Some states require mental health to be covered

If your business operates in certain states, you’re already legally obligated to let employees use sick leave for mental health:

• California: Covers physical or mental illness under the state’s paid sick leave law.
  
• New York: Includes mental health and preventive care as valid uses of paid sick time.
  
• Oregon, Washington, New Jersey: All allow sick leave for mental or behavioral health needs.

If your policy doesn’t reflect that, you’re potentially out of compliance.

FMLA doesn’t apply to most small businesses

The Family and Medical Leave Act (FMLA) allows unpaid leave for serious mental health conditions, but only applies to employers with 50 or more employees. That rules out most small businesses. And even if it does apply, FMLA is for long-term leave, not single mental health days.

In other words: If you’re a smaller business and your team is dealing with day-to-day burnout or stress, FMLA won’t cover it, but your sick leave policy can.

Clarity protects you and your team

Even if your state doesn’t mandate mental health coverage under sick leave, nothing prevents you from allowing it. But your paid sick leave policy must be clear. Employees need to know what’s allowed, and you need consistency in how time off is tracked or you risk miscommunication, resentment, or even legal complaints.

When your policy is clear, your compliance risk goes down and your employees feel protected working in an environment where their mental health challenges are taken seriously. 

Is offering sick leave for mental health good for your business?

Short answer: Yes.

Allowing employees to use sick time for mental health is a practical move that directly impacts productivity, retention, and team performance.

Here’s how it’s good for your business:

1- It prevents burnout before it becomes a bigger problem

When people don’t take time to reset, stress compounds. That’s when you start seeing missed deadlines, customer service slip-ups, and unplanned absences. Letting someone take a day off to mentally recover is cheaper and easier than covering for someone who crashes and needs weeks off.

A Gallup study found that burned-out employees are 63% more likely to take a sick day and 2.6x more likely to look for a new job. Giving your team room to breathe actually keeps them working longer and working better.

2- It reduces turnover and hiring costs

Turnover is expensive, especially for small teams. Replacing a single employee can cost from 33% up to 200% of their annual salary, according to the Work Institute. Mental health days help retain talent by showing employees that their well-being is as important as their output.

3- It builds a culture people want to stay in

Remember the email exchange between Madalyn Parker and her CEO we mentioned earlier? That’s a perfect example of the kind of culture mental health days help create: One built on trust, empathy, and understanding.

When employers acknowledge real human needs, people take pride in where they work. That’s especially true in small businesses, where culture is more personal and every team member plays a bigger role. Allowing sick leave for mental health sends a clear message: “We trust you to know when you need a break.” That trust builds loyalty and loyalty builds stability.

Does it have bookkeeping and payroll implications?

Allowing mental health days under existing sick time doesn’t change how much time off you offer but it does require that you track and categorize it correctly. Otherwise, you open yourself up to payroll errors, compliance issues, or even tax reporting problems.

Here’s how you can keep it streamlined:

1- Track it like any other sick leave

From a payroll perspective, mental health days should be treated just like any other use of sick time. That means:

• Logged under sick leave hours (not vacation or unpaid time)
• Paid at the employee’s regular rate, if sick time is paid
• Counted toward any state-required sick leave minimums (where applicable)

If you’re in a state that mandates paid sick leave, mental health days must be tracked as part of that pool, not separately.

2- Be consistent 

If your policy allows sick leave for mental health, you need to apply it consistently across all employees. That means having clear documentation, updating your employee handbook (if you have one), and training whoever processes payroll to code that time properly.

Inconsistent practices, like letting one person use a sick day for anxiety but denying it to another, can lead to employee complaints, low morale, or even legal issues in states with strict labor laws.

3- Automate your systems

If you’re still doing payroll manually or using basic spreadsheets, this is where mistakes happen. Mislabeling time off can lead to:

• Incorrect paychecks
• Misreported wages
• State noncompliance (especially if you’re subject to sick leave tracking laws)

The fix is simple: use a system that tracks leave categories properly and syncs with your payroll. Or, work with a payroll service that handles it for you, especially one that understands the compliance landscape for small businesses.

The bottom line

Allowing your employees to use sick leave for mental health is a policy adjustment that recognizes health isn’t just physical; it includes stress, burnout, and mental fatigue that directly impact an employee’s ability to perform their job.

But like any policy change in an organization, the details matter. While letting employees use sick time for mental health is a small policy shift, it also impacts your books: if time off isn’t tracked properly, it throws off payroll. If payroll’s off, your reports are off. And if your reports are off, your compliance risk climbs. 

That’s why it’s essential to keep your records accurate, and that’s only possible with proper bookkeeping and accounting.
