New Hire Turnover: Why Employees Leave in the First 90 Days

Hiring someone is only the beginning. An employee may accept the job, complete onboarding, and still leave within the first few months.

This is known as new hire turnover or early employee turnover.

When new employees leave within their first 90 days, employers may need to restart the recruitment process, spend more time training another employee, and deal with disruption to the team.

Understanding why new hires leave can help employers improve recruitment, onboarding, management, and employee retention.

What Is New Hire Turnover?

New hire turnover refers to employees leaving an organisation relatively soon after joining.

There is no single universal period used to define new hire turnover. However, employers often pay particular attention to employees who leave during their first few months, including the first 30, 60, or 90 days.

For example, if a company hires 50 employees and 8 leave within their first 90 days, those departures represent an important early turnover issue for the company to investigate.

New hire turnover can include employees who:

Resign voluntarily
Leave because the job does not meet their expectations
Leave for another opportunity
Are dismissed during probation
Decide the company or role is not suitable for them

Tracking these departures separately from overall employee turnover can help HR identify problems affecting new employees.

Why Do New Employees Leave in the First 90 Days?

There is rarely one reason why a new hire leaves.

The problem can start during recruitment and continue through onboarding and the employee's first few weeks.

The Job Does Not Match Expectations

One of the biggest risks occurs when the job advertised does not match the actual role.

For example, a job description may describe a position as:

"Marketing Executive"

But the employee discovers after joining that most of the work involves sales, customer support, or administrative tasks.

This mismatch can create frustration and cause the employee to reconsider the job.

Employers should make sure job advertisements accurately describe:

Main responsibilities
Working hours
Work location or arrangement
Required skills
Reporting structure
Expected targets
Travel requirements
Salary and benefits, where appropriate

Being clear during recruitment can help candidates make a more informed decision before accepting the role.

The Recruitment Process Created Unrealistic Expectations

The problem may begin before the employee joins.

Recruiters and hiring managers may unintentionally create expectations about:

The role
Career progression
Salary increases
Working arrangements
Benefits
Company culture
Training opportunities

If the employee discovers that the reality is very different, disappointment can develop quickly.

A good recruitment process should provide candidates with an accurate picture of the job rather than simply trying to convince them to accept an offer.

Poor Onboarding

Starting a new job can be overwhelming.

New employees need to understand how the company works, what is expected of them, who they should work with, and where they can get help.

Without proper onboarding, employees may feel:

Confused
Unprepared
Isolated
Uncertain about their responsibilities
Unsure about company expectations

Onboarding should therefore go beyond completing paperwork on the first day.

A structured onboarding process can include:

Company introduction
Role and responsibility briefing
System and tool access
Training
Team introductions
Manager check-ins
Clear short-term goals

The Manager Does Not Provide Enough Support

A new employee often relies heavily on their manager during the first few months.

If the manager provides little guidance, unclear instructions, or inconsistent feedback, the employee may struggle to understand whether they are performing well.

Regular check-ins can help managers identify problems early.

For example:

First week: Check that the employee understands the role and has the tools they need.

First month: Discuss progress, challenges, and training needs.

First 60–90 days: Review performance, expectations, and future goals.

These conversations also give employees an opportunity to raise concerns before they become serious problems.

The Employee Does Not Receive Enough Training

A new employee cannot always be expected to perform at full speed immediately.

They may need time to understand:

Internal systems
Processes
Products or services
Customers
Team responsibilities
Company policies
Job-specific skills

If an employee is given responsibilities without enough training or support, they may feel that they were not properly prepared for the role.

Employers should identify the skills a new hire needs and create a realistic training plan.

Company Culture Does Not Match Expectations

Candidates may also evaluate the company culture after joining.

During recruitment, an employer may describe the workplace as collaborative, flexible, supportive, or fast-paced.

If the employee experiences something very different after joining, they may question whether the company is right for them.

This is another reason employers should be honest about workplace culture during recruitment.

Instead of presenting only the positive side, explain how the team actually works.

The Employee Does Not See a Future With the Company

Some employees leave because they do not see opportunities to grow.

They may want:

Career progression
More responsibility
Training
New skills
Leadership opportunities
A clearer career path

This does not mean every new employee needs a promotion within 90 days.

However, employees should understand how their role can develop over time.

Managers can discuss career goals early and explain what skills or performance are needed for future opportunities.

Communication Problems

Poor communication can quickly create frustration for a new employee.

Examples include:

Unclear instructions
Slow responses
Conflicting information
No regular feedback
Not knowing who to approach for help

New employees should know who they report to, where to get support, and how important information is communicated.

Clear communication is especially important during the first few weeks.

The Employee Finds a Better Opportunity

Sometimes the reason is simple: another employer offers something the employee prefers.

This could include:

Higher salary
Better benefits
Flexible working arrangements
Better career opportunities
Shorter commute
More suitable working hours
A role that better matches their interests

Employers cannot prevent every employee from leaving for another opportunity.

However, understanding why new hires leave can help identify whether there are recurring issues within the company's recruitment or employment experience.

How to Calculate New Hire Turnover Rate

Employers can create a simple metric to track early employee turnover.

For example:

New Hire Turnover Rate = (Number of New Hires Who Leave Within a Defined Period ÷ Total Number of New Hires) × 100

Suppose a company hires 100 employees during a quarter.

Within their first 90 days, 12 employees leave.

The calculation would be:

(12 ÷ 100) × 100 = 12%

The company's 90-day new hire turnover rate would therefore be 12% for that group.

The important thing is to define the period consistently.

For example, HR could track:

30-day turnover
60-day turnover
90-day turnover
6-month turnover
12-month turnover

This makes it easier to compare different hiring periods and identify changes over time.

What Does a High New Hire Turnover Rate Mean?

A high new hire turnover rate does not automatically mean that the company has a serious HR problem.

Some employees may leave because the role is not suitable for them, they receive another opportunity, or their circumstances change.

However, consistently high early turnover can be a warning sign.

HR should investigate questions such as:

Are employees leaving from the same department?
Are they leaving under the same manager?
Are they leaving at the same point in the first 90 days?
Did they receive enough onboarding?
Was the job accurately described during recruitment?
Are employees mentioning similar reasons for leaving?
Is the turnover higher for certain roles?

Looking for patterns is more useful than focusing on one individual resignation.

How to Reduce New Hire Turnover

Improve Job Descriptions

Make job advertisements accurate and specific.

Clearly explain the responsibilities, requirements, working arrangements, and expectations of the role.

Set Realistic Expectations During Interviews

Recruiters and hiring managers should provide candidates with an honest view of the position.

Explain both the opportunities and the challenges of the role.

Create a Structured Onboarding Process

Prepare a clear onboarding plan covering the employee's first day, first week, first month, and first 90 days.

Give New Employees Clear Goals

Employees should understand what is expected of them.

Instead of giving vague instructions, establish clear priorities and short-term objectives.

Schedule Regular Check-Ins

Do not wait until the end of probation to ask how the employee is doing.

Regular conversations can help identify problems early.

Provide Enough Training

Make sure employees receive the training, resources, and access they need to perform their roles.

Encourage Questions and Feedback

New employees may hesitate to raise concerns because they are still getting comfortable.

Managers should create an environment where asking questions is normal.

Review the Recruitment-to-Onboarding Process

Look at the entire employee journey:

Job Advertisement → Application → Interview → Offer → Onboarding → First 90 Days

If new hires are leaving early, the problem may not start after they join.

It could begin with how the role was advertised, how expectations were communicated, or how candidates were evaluated.

How Recruitment Affects New Hire Turnover

New hire turnover is not only an onboarding issue.

Recruitment decisions can have a major impact on what happens after someone joins.

For example:

Unclear Job Advertisement

↓

Wrong Candidate Expectations

↓

Candidate Accepts the Job

↓

Reality Does Not Match Expectations

↓

Employee Leaves Early

This is why employers should focus on both hiring the right person and providing the right information before the person joins.

A strong recruitment process should help candidates understand the role and help employers evaluate whether the candidate is suitable for it.

How Candidate Feedback Can Help

Employers can also ask new employees about their recruitment and onboarding experience.

Useful questions include:

Did the actual role match what was explained during recruitment?
Was the job description accurate?
Did you receive enough information before joining?
Was the onboarding process helpful?
Did you understand your responsibilities?
Did you receive enough training?
Did your manager provide enough support?
What could we have done better?

This feedback can help HR identify problems that may otherwise be missed.

For example, if several new employees say that the actual role was different from what they expected, the company may need to review its job descriptions and interview process.
