Why 80% of Menstruators Experience Productivity Loss at Work (And What Employers Can Do)

Why do 80% of menstruators experience productivity loss at work? Research shows that unmanaged physical symptoms, paired with a lack of cycle awareness in the workplace, directly reduce cognitive focus and physical stamina. At Cyclical School, we teach that supporting hormonal balance through education and flexible policies is the most effective way for organisations to rebuild workplace productivity and employee well-being.

Why 80% of Menstruators Experience Productivity Loss at Work

What Does Productivity Loss Mean for Menstruators?

Productivity loss for menstruators goes far beyond taking a sick day. It includes a range of challenges that affect how well someone can perform their daily tasks. For instance, it can mean a reduction in focus, making detailed work feel overwhelming and increasing the chance of errors. It also involves working at a slower pace, where managing the usual daily workload becomes a significant hurdle. This drop in capacity can also look like:

• Needing frequent breaks to manage physical discomfort
• Experiencing a lack of motivation due to low energy
• Using mental energy to hide symptoms from coworkers during meetings

Many individuals continue to show up to work even when they are unwell. This is known as presenteeism. They are physically present but unable to function at their normal baseline. Over time, presenteeism often costs a business more than formal sick leave because the lower output is hidden and can last for several days of the month.

How Many Employees Are Affected: Key Statistics

The 80% figure is strongly supported by global research. A peer-reviewed study in the BMJ involving over 32,000 menstruators found that 80.7% reported presenteeism, resulting in an average of 23.2 days of lost productivity per person each year. This is not a rare workplace issue; it affects a massive portion of the workforce globally. In Australia, conditions like heavy menstrual bleeding, endometriosis and polyendocrine metabolic ovarian syndrome (PMOS) affect millions, further impacting workplace performance. By recognising how widespread these challenges are, workplaces have a clear opportunity to support their staff and encourage sustainable lifestyle practices.

What Are the Most Common Symptoms Impacting Work Performance?

While everyone experiences their cycle differently, certain symptoms frequently interfere with work. Severe cramps, back pain and migraines can make it incredibly difficult to concentrate. Leading a meeting or making careful decisions while in physical distress is a heavy burden. Other common cycle-related challenges include:

• Fatigue that makes it difficult to maintain energy levels throughout the day
• Brain fog that impacts memory, logical thinking and quick decision-making
• Heavy bleeding that creates anxiety around leaks and requires constant bathroom trips
• Low iron resulting from heavy bleeding, which can contribute to weakness and dizziness
• Mood shifts such as irritability or feeling low, which can change how people collaborate

Even a single symptom can lower performance. When multiple symptoms occur at once, keeping up with normal professional demands requires an immense amount of effort.

What Causes Productivity Loss Among Menstruators at Work?

Physical Symptoms: Pain, Fatigue and Heavy Bleeding

The physical realities of the menstrual cycle are frequently dismissed in professional settings. For many, pain is severe but remains unspoken. Endometriosis, for example, can cause intense pain that extends well beyond the menstrual phase. Heavy bleeding requires constant management, often leading to iron deficiency which further depletes energy. Managing these physical demands drains a person’s energy reserves. That energy is diverted away from problem-solving, creativity and speed at work. Reconnecting with your body and understanding these cues is vital, but doing so in a rigid work environment is often impossible.  

Mental and Emotional Challenges During the Menstrual Cycle

Hormonal shifts across the different cycle phases naturally influence mood and cognitive function. During the premenstrual or luteal phase, some menstruators experience heightened stress sensitivity, anxiety or brain fog. This makes it harder to retain details or make clear decisions. These emotional shifts can also change:

• How individuals communicate with their team or clients
• Their capacity to handle strict deadlines and high-pressure feedback
• Their patience when working collaboratively in group settings

Using up energy to act completely unaffected by these hormonal changes is exhausting and quietly reduces overall output.

Absenteeism Versus Presenteeism: How Symptoms Influence Attendance

As mentioned earlier, menstrual symptoms affect workplace attendance in two distinct ways. Understanding the difference is key to providing the right support.

Type	What it looks like	Why it matters
Absenteeism	Taking official sick leave due to severe cycle symptoms.	It is easy to track, but many avoid taking it due to fear of judgement.
Presenteeism	Coming to work unwell and operating below normal capacity.	It is harder to measure but often leads to greater long-term productivity loss and burnout.

When presenteeism goes unaddressed, the cycle of pushing through pain continues, negatively impacting both the individual and the wider team.

Lack of Access to Menstrual Products or Facilities

Practical barriers easily create unnecessary stress. If a period arrives unexpectedly and the workplace lacks basic supplies, the result is panic, distraction and lost time. Access to clean, private and well-stocked bathrooms is essential. Common facility issues include:

• No free menstrual products available for staff
• Inadequate disposal bins or unhygienic environments
• Bathrooms that lack the privacy needed to manage heavy bleeding comfortably

Providing free products in all restrooms is a simple, cost-effective way to support dignity and keep the workday running smoothly.

Stigma and Discomfort Around Discussing Menstruation

Stigma remains one of the largest barriers to cyclical living in the workplace. Many individuals feel they cannot discuss period symptoms with their managers for fear of being viewed as incapable. This silence forces them to push through their symptoms without any adjustments. This culture of silence often begins early in life. Many students miss school or struggle to concentrate due to a lack of menstrual education and basic facilities. When teens learn to hide their periods, they carry that exact same silence into their adult working lives. Normalising menstrual health through education helps people feel comfortable asking for the support they need.

How Does Menstrual-Related Productivity Loss Affect Workplaces?

Lost Work Hours and Hidden Costs

The financial impact of cycle-related challenges extends far beyond a few days of sick leave. Research indicates that menstrual symptoms cost the Australian economy billions of dollars annually. These costs are a mix of direct expenses like paid leave and hidden costs tied to lower daily output. When employees are working through pain or brain fog, workplaces typically see:

• A drop in the quality of work produced
• Missed deadlines and delayed project timelines
• An increase in errors requiring extra time to fix

Impact on Team Dynamics and Morale

When an employee regularly struggles at work, the rest of the team often has to absorb the overflow. This can create pressure, disrupt schedules and eventually lead to collective burnout. Furthermore, an environment where staff feel forced to hide their health needs breaks down mutual trust. Supportive teams function much better when everyone feels understood and safe enough to communicate their limits.

Retention, Recruitment and Gender Equity Implications

A survey by the CIPD found that over half of menstruators have had to take time off due to their symptoms, yet many feel unable to disclose the real reason to their managers. Workplaces that ignore menstrual health risk losing talented staff to more inclusive organisations. There is also a clear gender equity factor. If menstruating employees face constant barriers because their cyclical needs are ignored, it can impact their performance reviews and career progression. Supporting menstrual health is an essential part of building a fair, modern workplace.

What Are the Benefits of Addressing Menstruation at Work?

Improved Productivity and Employee Engagement

When employers actively support menstrual cycle awareness, staff can manage their symptoms proactively and return to their normal pace much sooner. Proper support reduces presenteeism because employees spend less mental energy trying to hide their discomfort. This results in sharper focus and a smoother workflow. Employees who feel their natural rhythms are respected are also far more engaged. They are motivated to contribute and feel a stronger loyalty to their organisation.

Increased Retention and Reduced Sick Leave

Accommodating cyclical health improves staff retention. When people feel valued, they stay. Offering flexible working arrangements can also reduce the need for someone to take a full sick day. For example, allowing an employee to work from home during their heaviest flow day keeps work moving while supporting their physical needs.

Positive Workplace Culture and Inclusivity

Treating the menstrual cycle as a normal aspect of human health builds an inclusive culture. It removes the shame attached to bleeding and encourages open dialogue. A workplace that visibly supports different bodily needs naturally attracts a wider, more diverse pool of talent.

What Can Employers Do to Support Menstruators in the Workplace?

1. Providing Access to Period Products and Facilities

The easiest action an employer can take is supplying free pads and tampons in all workplace bathrooms. This simple step removes the anxiety of being caught off guard. Employers must also ensure that restrooms are:

• Clean, private and comfortable
• Regularly stocked with supplies
• Fitted with appropriate disposal bins in every stall

2. Implementing Menstrual Leave or Flexible Work Options

Introducing a menstrual leave policy shows genuine commitment. This can sit within existing personal leave or function as a separate offering. Beyond leave, flexible work options are incredibly effective for working with your natural rhythms. Helpful adjustments include:

• Allowing staff to work remotely on difficult days
• Offering flexible start and finish times
• Temporarily shifting demanding tasks during peak symptom days

3. Designing Supportive Policies and Procedures

Workplace support should be documented and clear. Employers can weave menstrual health into their broader well-being strategies. Having a written procedure for requesting support ensures that managers handle conversations confidentially and consistently across the board.

4. Raising Awareness and Reducing Stigma Through Education

Education replaces confusion with understanding. Workplaces can host internal workshops to teach all staff, including non-menstruators, about the realities of cycle phases. Just as schools are beginning to integrate cycle education for students, workplaces must also adopt basic cycle awareness training. To deepen this support, HR professionals and managers can enrol in a Menstrual Cycle Coaching Course. Training an internal advocate helps teams successfully implement supportive frameworks and sustainable lifestyle practices.

5. Encouraging Open Communication With Staff

Leaders set the tone for the entire organisation. Regular, private check-ins and anonymous feedback channels make it easier for employees to express what they need. When staff know they will be met with empathy, they are more likely to communicate early.
