A restless night. Brain fog in a meeting. A sudden hot flush before a presentation.
For some women, perimenopause arrives during demanding career years.
It is a normal life stage, but symptoms can affect sleep, concentration, energy and comfort at work. And many employees still hesitate to talk about it.
Key Takeaways
- Perimenopause can involve poor sleep, fatigue, hot flushes, mood changes and difficulty concentrating.
- A 2025 Asia-Pacific survey found that nearly half of working women reported significant disruption to work or daily activities from menopausal symptoms.
- Employees in Singapore can formally request flexible work arrangements, although approval is not automatic.
- Practical flexibility and informed managers can help without treating perimenopause as a performance problem.
What Is Perimenopause?
Perimenopause is the transition leading up to menopause.
Hormone levels fluctuate and symptoms may continue for several years.
Possible symptoms include:
- Hot flushes and night sweats
- Poor sleep
- Fatigue
- Mood changes
- Difficulty concentrating
- Headaches
- Changes in menstrual cycles
Symptoms vary considerably. Some women experience little disruption, while others find that work and daily life become noticeably harder.
How Can Perimenopause Affect Work?
Nearly half reported significant disruption to work or daily activities, while 61% said stigma made it harder to discuss symptoms or seek support.
At work, someone may simply appear:
- More tired after poor sleep
- Less focused than usual
- Uncomfortable in a warm environment
- More dependent on breaks
- Temporarily less able to manage inflexible hours
That does not mean perimenopause reduces someone’s competence.
It means symptoms can sometimes make doing the job harder than it needs to be.
What Can Employees Do?

You do not necessarily need to share every medical detail.
Focus on what is affecting your work and what might help.
For example:
“My sleep has been disrupted recently and early mornings are difficult. Could we discuss temporarily adjusting my start time?”
Possible adjustments might include:
- Flexible start and finish times
- Working from home where suitable
- Short breaks
- Better ventilation or a cooler workspace
- Adjusting when highly demanding tasks are scheduled
If symptoms are persistent or affecting your quality of life, speak with a healthcare professional rather than assuming you simply have to tolerate them.
What Can Employers Do?
Support does not need to begin with a complicated menopause policy.
Build Manager Awareness
Managers should understand that symptoms can affect sleep, concentration, energy and physical comfort — not only cause hot flushes.
Ask What Would Help
Do not assume every employee needs the same adjustment.
A practical conversation is often more useful than trying to interpret someone’s medical condition.
Protect Privacy
Employees should not feel pressured to discuss intimate health information with colleagues.
The aim is to make support easier to access, not turn perimenopause into a workplace label.
Can Employees Request Flexible Work?
Yes.
- Flexi-time
- Flexi-place
- Flexi-load
The guidelines took effect on 1 December 2024.
Employers must properly consider formal requests and respond within two months, although they may reject requests for legitimate business reasons.
Flexible work is therefore not automatically guaranteed.
But employees have a recognised process for asking.
Frequently Asked Questions
Do I Have to Tell My Manager It Is Perimenopause?

Not necessarily.
You can explain how your health is affecting your work and what adjustment might help without sharing more medical information than you are comfortable with.
Can I Request Flexible Working Hours?
Yes.
You can submit a formal flexible work arrangement request. Your employer must properly consider and respond to it, although approval is not guaranteed.
Does Brain Fog Mean My Memory Is Permanently Affected?
Not necessarily.
Difficulty concentrating or remembering things can occur during the menopausal transition and may also be worsened by poor sleep. Speak with a healthcare professional if symptoms are persistent or concerning.
The Bottom Line
Perimenopause is not a performance problem.
But symptoms can make work temporarily harder for some women.
Employees should not have to struggle silently, and employers do not necessarily need elaborate new policies to respond well.
Often, the starting point is simpler:
Recognise what is happening.
Talk about what would help.
Use practical flexibility where possible.
That can help experienced employees continue doing their jobs well without treating a normal health transition as something they need to hide.
