Why Your Work Schedule Was Built for a Man (And What Women Actually Need)

Stacy Sims emphasizes that this is a guideline habit, not a rigid rule. She describes how women commonly report the mid-luteal phase as a time of lower energy and mental fog. However, she immediately cautions that hormone responses are highly individualized, citing that she has met people who feel 'immensely better when progesterone's present.' She foregrounds the importance of cycle tracking as a tool for self-knowledge. Her partner Mel serves as a personal example: Mel identifies a couple of low-stress-tolerance days each month, uses them for nesting or lighter work, and stacks harder tasks on better days. The overarching message is that giving women the autonomy to do this kind of self-directed allocation, supported by workplace flexibility, lifts productivity overall because work still gets done—just redistributed across the month.

The speaker describes New Zealand companies that, especially post-pandemic, implemented flexible hours, 4-day workweeks, and menstrual/menopause leave baked into annual leave. The key innovation is that the leave is not siloed—you don't have to declare it as a cycle day. It's simply extra time off that people use for cramps, mental health, or childcare disruptions. This anonymity lowers the psychological friction of requesting time for a still-stigmatized reason. As a result, the workforce experiences higher empowerment, inclusivity, and a sense of being trusted, which feeds back into engagement and output. The speaker argues that when workers can decide when to push hard and when to pull back, overall delivery remains high, often surpassing the output of a rigid daily quota system.

The expert highlights that 'we hear all the stuff about cycle tracking' but frames it as a tool for learning your own hormone flux responses, not just fertility. The goal is to move from generic advice (avoid stress in luteal) to personalized data that tells you when you actually feel best. Her partner's experience illustrates this: she noticed a couple of nesting days and used that insight to reshuffle tasks. Stacy stresses that without this self-awareness, women might force themselves to perform at a uniform level all month, risking burnout or subpar work during biologically low tides. Tracking is presented as the foundational step before implementing any phase-based task allocation.

The speaker argues that while full-time on-site childcare is a major undertaking, a stopgap emergency service is a more accessible entry point that still delivers substantial ROI. She describes the stress of a last-minute childcare gap: calling out of work, missing responsibilities, and the mental load of cobbling together coverage. Having a trusted, on-campus option for those crisis days removes that cognitive and emotional burden. This security translates into loyalty and harder work because employees feel seen and supported. The speaker even claims that companies offering such benefits would attract 'the most competitive workforce,' turning what looks like a cost center into a talent magnet.

The speaker describes how, especially after the pandemic, some New Zealand employers have adopted 4-day work weeks and flexible hours, integrating menstrual or menopause leave into annual leave pools. Employees simply say they can't come in on a given day, and the reason remains private. This policy is used not only for severe menstrual cramps but also for mental health days or childcare emergencies. The critical insight is that anonymity and the lack of a requirement to 'prove' a cycle-related issue remove guilt and shame, allowing women to manage their energy and well-being proactively. As a result, people still get their work done, often front-loading tasks when they feel better. The company benefits from higher loyalty and overall output because the workforce feels trusted. The speaker argues that such flexibility fosters an inclusive culture that feeds forward into better productivity and retention.

Stacy Sims explains that during the follicular phase (roughly the first 14 days after menstruation, before ovulation), estrogen is dominant and progesterone is low. For most people, this hormonal environment supports better focus, concentration, and stress tolerance, making it the ideal window for deep work like writing papers or completing complex analyses. In contrast, the mid-luteal phase (middle of the second half of the cycle) brings high progesterone, which is associated with fatigue, reduced energy, and brain fog. The body is physiologically preparing for potential implantation, and many report harder time focusing. However, she stresses that these are averages—some individuals feel better when progesterone is present. She uses the example of her partner Mel, who notices a couple of days each month when she needs to 'nest' and has lower stress tolerance. The key takeaway is not to blindly follow a calendar but to track one's own cycle and responses, then allocate demanding tasks accordingly. Employers who grant flexibility can harness this self-awareness for better performance.

Sims argues that while full-time on-site childcare is a major commitment, even a modest emergency backup program is money well spent. She explains that if a woman's regular nanny no-shows or a child becomes sick, the alternative is often calling out of work, which disrupts productivity and creates stress. Having a dedicated on-campus emergency care solution—where the child isn't there full-time but can be accommodated on an ad-hoc basis—breeds deep loyalty. The speaker suggests that a company offering such support would create a highly competitive workforce because it directly eases the conflicting demands of motherhood and career. This low-barrier intervention signals genuine investment in employees' lives, translating into higher engagement and output.

This policy was raised as a contrast to the American system, which the host acknowledged as lacking. In New Zealand, children start school on their fifth birthday, and until then, 20 hours of daycare per week are fully funded. Additional hours require only a small nominal fee. The speaker notes that this support 'does help significantly' to keep productivity and alleviate the worry of 'what am I going to do with my child?' It acts as an enabler for mothers to stay in the workforce and perform without constant anxiety about childcare logistics. While the speaker does not suggest that every country can instantly adopt the policy, presenting it highlights that employer-level stopgap solutions exist within a larger systemic context, and that government support can make a measurable difference.
