When HR professionals and managers receive training on menopause in the workplace, one of the most common responses is: ‘I had no idea it started so early.’ Menopause itself — defined as twelve consecutive months without a menstrual period — typically occurs around age 51. But the transition to menopause, known as perimenopause, can begin a full decade before that.
Understanding perimenopause is essential for anyone supporting a workforce. It is the phase when symptoms are often at their most unpredictable and disruptive — yet it is also the phase that goes most unrecognised.
What Is Happening Biologically?
From puberty onwards, a woman’s menstrual cycle is governed by the rise and fall of hormones — principally oestrogen and progesterone — produced by the ovaries. As a woman approaches her 40s, the ovaries begin to produce these hormones less consistently. The result is a period of hormonal fluctuation that can last anywhere from two to twelve years.
This is perimenopause. It is not a single event but a gradual process, and it is characterised by unpredictability. Periods may become irregular — heavier, lighter, closer together, or further apart. Hormones can swing sharply within a single day or week. It is this volatility, rather than the eventual low levels of menopause itself, that drives many of the most disruptive symptoms.
What Does Perimenopause Look Like at Work?
Because perimenopause is not widely understood, its effects are frequently misattributed — to stress, burnout, mental health difficulties, or simply ‘having a hard time.’ This misattribution matters, because it leads to the wrong interventions, or no intervention at all.
Common symptoms that affect workplace performance include:
- Cognitive changes — difficulty concentrating, memory lapses, and a sense of ‘brain fog’ that can feel alarming to a woman who has always been sharp and capable.
- Sleep disruption — night sweats and insomnia leave employees arriving at work already exhausted, with reduced capacity for sustained focus or complex decision-making.
- Mood changes — anxiety, low mood, and irritability that are hormonally driven and can be misread as interpersonal or performance issues.
- Physical symptoms — hot flushes, palpitations, joint pain, and headaches that are unpredictable and difficult to manage in a work environment.
- Heavy or irregular periods — causing physical discomfort, unplanned absences, and significant practical difficulties in the workplace.
A senior manager forgetting a name in a meeting, an experienced administrator making uncharacteristic errors, a long-standing employee who has become quieter and more withdrawn — any of these could be perimenopause. Without awareness, these signals are invisible.
When Does It Start — and Who Is Affected?
Perimenopause can begin as early as the late 30s, though it more commonly starts in the mid to late 40s. The average age of menopause in the UK and Caribbean is 51, which means the perimenopausal transition is often well underway before many women — or their employers — would think to consider it.
It is also worth noting that some women experience premature ovarian insufficiency (POI), in which menopause occurs before the age of 40. This is not rare — it affects approximately 1 in 100 women under 40 — and it can be particularly isolating because it falls so far outside the expected timeline.
Surgical menopause — following hysterectomy with removal of the ovaries — produces an abrupt rather than gradual hormonal change and can result in particularly severe symptoms. Any workforce is likely to include women navigating this experience, often with little support.
What Does This Mean for HR?
The practical implications are straightforward. HR professionals and managers do not need to become medical experts. What they need is enough understanding to:
- Recognise that a colleague in her 40s may be experiencing perimenopause, even if she has not named it as such.
- Know how to open a sensitive, supportive conversation without making assumptions.
- Understand what reasonable adjustments might help — and be empowered to offer them.
- Avoid conflating perimenopausal symptoms with performance or conduct issues.
- Signpost to occupational health, Employee Assistance Programmes, or medical support where available.
Perhaps most importantly, HR professionals who understand perimenopause can help create a culture in which women feel safe naming their experience. That psychological safety is the foundation of everything else.
MenoHealth Academy’s HR Champion Training equips your people managers with exactly this foundation — practical, evidence-based, and designed for the Caribbean workplace.
