The “Sorry Tax” in project delivery
When Sheryl Sandberg published Lean In in 2013, one observation resonated across professional environments, including project and programme delivery: women apologise more frequently than men at work, not for errors, but for speaking, questioning, interrupting, or asserting professional judgement.
Research confirms this pattern. Women apologise more often because they perceive a wider range of behaviours as risky or potentially penalised not because they are less capable, but because professional consequences are unevenly applied (Schumann & Ross, 2010). Sandberg also articulated the now well-established double bind: women who behave assertively can be judged as abrasive, while those who soften their approach may be seen as lacking authority.
For project professionals, this matters directly. Effective project delivery depends on challenge, escalation, decision-making under uncertainty and ethical leadership, all core Ƶ competencies. If some voices feel the need to soften or preface their contributions to avoid backlash, delivery quality is compromised. This is not a confidence issue; it is a systemic risk to governance and assurance.
The gender pay gap and cumulative impact on project careers
Despite sustained attention to equality, the UK gender pay gap remains measurable. The Office for National Statistics reports that the median gender pay gap among full-time employees was , widening with age. This pattern reflects a cumulative disadvantage linked to caregiving, career interruptions and slower progression - not differences in skill or commitment.
Project careers are particularly exposed to this effect. Senior project, programme and portfolio roles often assume uninterrupted availability, travel and extended delivery peaks. When role design does not account for caregiving realities, organisations lose experienced practitioners at mid-career, precisely when strategic capability and leadership maturity are most valuable.
From an Ƶ perspective, this represents a capability sustainability issue: loss of experienced delivery leaders increases reliance on less experienced resources, weakens organisational memory and raises delivery risk.
Caregiving, SEND and the “second shift” in delivery roles
Women continue to carry the majority of unpaid caregiving. ONS time-use data shows women spend 3 hours and 37 minutes per day on unpaid work, 54 minutes more than men. For parents of children with Special Educational Needs and Disabilities (SEND), caregiving is often continuous and unpredictable, involving coordination across education, health and care systems.
Many women in project roles are also part of the sandwich generation, caring for both children and ageing parents. This pressure typically intensifies during mid-career, the same period when project professionals are expected to demonstrate advanced competence in resource management, leadership, stakeholder engagement and decision-making.
When organisations fail to design delivery systems that accommodate this reality, the result is not reduced competence it is attrition. From a professional practice standpoint, this undermines ethical leadership and sustainable delivery, both central to Ƶ’s values.
Flexibility, role design and the leadership ceiling
Women frequently step into roles below their capability or delay applying for promotion, because senior roles are widely assumed to involve long hours, limited flexibility and constant availability. This assumption reflects labour market reality.
The Timewise Flexible Jobs Index found that only 31% of UK job adverts mentioned flexible working in 2023. For roles paying £60,000 or more, only around 6% were advertised as part-time or open to job-share. This significantly narrows leadership pathways at the point when caregiving demands often peak.
This is not a talent pipeline problem; it is a role design problem. In project management terms, it reflects poor resource planning and an outdated view of utilisation that prioritises presence over outcomes.
Women are also more likely to delay applying for promotion until they feel fully qualified, while men tend to apply when meeting fewer criteria, a pattern well documented in management research. Combined with inflexible role design, this contributes to under-representation of women, particularly carers in senior delivery leadership.
The backlash effect: a risk to decision quality
Evaluation bias compounds these challenges. Rudman and Phelan (2008) demonstrated that assertive women are more likely to be judged less likeable or less hireable than equally qualified men, a phenomenon known as the backlash effect.
In project environments, this directly affects risk management and governance. If assertive challenge is discouraged or penalised, risks go unreported, assumptions remain untested and escalation is delayed. This undermines the very behaviours project managers are expected to demonstrate under the Ƶ Competence Framework.
Implications for project management practice
Women especially carers and SEND parents do not bring less to project delivery. They often bring enhanced prioritisation, stakeholder sensitivity, resilience and crisis management capability. What they lack is not competence, but systems designed around real working lives.
The next step in professional maturity is not asking individuals to cope better, but redesigning delivery environments to retain capability, support ethical leadership and strengthen assurance.
Ƶ practice checklist: Embedding inclusive project competence
Outcome-based performance:
Assess delivery on benefits, risk management and stakeholder outcomes, not visibility or hours.
Flexible governance:
Use predictable decision cycles, asynchronous papers and clear escalation thresholds.
Job-share and part-time leadership:
Treat shared leadership as a resilience strategy supported by structured handovers.
Care-aware resourcing:
Plan carers’ leave and flexibility as part of capacity management.
Bias-aware leadership development:
Train sponsors and leaders to recognise backlash effects and evaluation bias.
SEND-aware delivery design:
Recognise SEND caregiving as ongoing, not exceptional.
Final reflection
When women apologise before contributing, it is often not insecurity it is rational risk management in systems where penalties are unevenly applied. For project organisations, the cost is tangible: weaker challenge, reduced risk visibility and loss of experienced leadership.
Professional project management is about designing systems that deliver under constraint. If those systems require certain groups to endure more simply to participate, they are not demonstrating delivery maturity.
The future of project management lies not in greater resilience from individuals, but in better design from organisations.
