How to Set Up Employee Leave Policies (Without an HR Department)

You started a business, not an HR department. But now you have employees, and they need time off, and you need rules for how that works. Maybe you've been handling it informally — "just let me know when you need a day" — and it worked fine when you had 3 people. Now you have 10 or 15 and it's getting messy.

This guide walks you through setting up real leave policies from scratch. No HR jargon. No 40-page employee handbook templates. Just the decisions you need to make, in the order you need to make them.

Step 1: Decide what types of leave you'll offer

Before you set any numbers, figure out which categories of time off your business will have. Here are the most common types:

The simplest approach is a single PTO bucket that combines vacation and personal time, plus a separate sick leave bucket (which many states now require). This is what most small businesses under 50 employees use.

Check your state requirements first

Before you decide what to offer, check what your state requires. As of 2026, over 15 states and many cities mandate paid sick leave. Requirements vary:

• Accrual rate (e.g., 1 hour of sick leave per 30 hours worked)
• Annual cap (e.g., 40 or 48 hours per year)
• Carryover rules (whether unused sick time rolls over)
• Eligible employees (some states exclude small employers)

Your leave policy needs to meet or exceed these minimums. If your state requires 40 hours of paid sick leave per year, you can offer more, but you can't offer less.

Step 2: Choose your accrual method

This is the decision that trips up most business owners. How do employees earn their time off? There are two main approaches.

Front-loaded (lump sum)

Employees get their full annual allowance on a set date — usually January 1 or their hire anniversary. Simple to administer and easy for employees to understand. The downside: employees who leave early in the year may have used more time than they've "earned."

Gradual accrual (per pay period)

Employees earn a set amount of leave each pay period. If the policy is 15 days per year and you pay biweekly, they earn about 4.6 hours per paycheck. Lower risk if someone leaves mid-year, and it aligns with state sick leave accrual requirements. The downside: more complex to track manually, and new employees start with a near-zero balance.

Which one should you pick?

If simplicity is your priority and you trust your team, front-load it. If you want tighter control — especially with higher-turnover roles — use gradual accrual. Many businesses use front-loaded PTO for salaried employees and gradual accrual for hourly staff.

Step 3: Set carryover rules

What happens to unused leave at the end of the year? You have three options:

Use-it-or-lose-it. Unused PTO expires at year end. Keeps liability low, but some states (California, Montana, Nebraska) prohibit this entirely.

Unlimited carryover. Everything rolls over. Simple, but your liability grows every year.

Capped carryover. Employees can carry over a set number of hours (e.g., 40 hours) and the rest expires. This is the most common approach. A typical policy: "Employees may carry over up to 40 hours of unused PTO. Any balance above 40 hours is forfeited on January 1."

Step 4: Define probationary periods

New hires don't always get immediate access to leave. A probationary or waiting period is common — usually 30, 60, or 90 days.

During this period, you can choose to:

• Not accrue any leave (employees earn nothing until the period ends)
• Accrue but not use (time accumulates but can't be taken until probation ends)
• Full access from day one (no waiting period)

If your state mandates paid sick leave, check whether it allows a waiting period. Many require accrual to begin immediately, even if usage is restricted for the first 90 days.

For PTO and vacation, a 90-day waiting period is standard and widely accepted. It gives both you and the new hire time to confirm the job is a fit before leave enters the picture.

Step 5: Handle the edge cases

Every leave policy needs answers to these questions. If you don't address them upfront, you'll end up making one-off decisions that create inconsistency and resentment.

What about part-time employees?

The standard approach is to prorate. If a full-time employee (40 hours/week) gets 15 days of PTO, an employee working 24 hours/week gets 9 days. Or you can offer the same number of days but count them as shorter days based on their typical schedule.

Can employees go negative?

Do you allow people to take PTO before they've accrued it? Some businesses allow a negative balance up to a limit (e.g., -16 hours). Others require a positive balance for every request. Decide this in advance.

What happens to unused PTO when someone leaves?

In some states, you must pay out accrued, unused PTO at termination. In others, it depends on your written policy. Check your state law, then put it in writing. The most common approach: pay out unused PTO, don't pay out unused sick time.

How much notice is required?

Set expectations. A common policy: planned leave requires 2 weeks' notice, sick leave requires notification before the start of the shift. This doesn't need to be rigid, but it gives managers a baseline.

Step 6: Write it down and enforce it

Your leave policy doesn't need to be long. A single page covering the points above is enough. What matters is that it exists in writing and every employee has access to it. Put it in your employee handbook, your onboarding docs, or a shared Google Doc.

But writing the policy is the easy part. Enforcing it consistently — tracking balances, applying accruals, handling carryover resets, flagging conflicts — that's where things break down.

The policy is the easy part. Enforcing it consistently — tracking balances, applying accruals, handling carryover resets, flagging conflicts — that's where things break down.

This is exactly why leave management software exists. You configure your policy once, and the system handles the math, the approvals, and the record-keeping.

TimeLeaf lets you set up everything covered in this guide — leave types, accrual methods, carryover caps, probation periods, part-time proration — in a single configuration screen. Most customers have their policies live in under 30 minutes.

You don't need an HR department to have a professional leave policy. You just need clear rules and a tool that enforces them. If you're ready to move past spreadsheets and informal arrangements, take a look at how TimeLeaf works and see if it's the right fit for your team.
