Mentoring: can you afford not to invest?
The competition for talent does not end when someone accepts a job.
Employees can perceive whether an organisation is serious about their future. Offering access to a credible external mentor sends a powerful positive signal: we see your potential, we are prepared to invest in you, and we want you to build your career here.
LinkedIn’s 2025 Workplace Learning Report found that 88% of organisations were concerned about employee retention. Gallup also found that 48% of employees who had participated in a mentoring programme during the previous year reported high job satisfaction, compared with 29% of those who had not.
For employers competing to attract and retain experienced people, mentoring provides visible, individual support. It gives employees access to one-to-one guidance, industry relevant experience and a trusted relationship focused on their development.
External mentoring can be particularly beneficial for high performers, people moving into larger roles and employees who have accumulated valuable organisational knowledge. These are the people competitors are keenest to recruit – and the most costly to replace.
Why external mentoring is different
Internal mentoring can be valuable. A senior colleague can share experience, offer guidance and help someone understand the organisation more deeply.
Internal programmes can be vulnerable to competing priorities, uneven commitment and existing organisational relationships. Meetings can be postponed, momentum fades and mentees may avoid discussing the issues that matter most because their mentor is part of the same hierarchy, culture or network.
An external mentor brings independence. They have no reporting line, agenda or internal position to protect. The mentee can speak openly about confidence, relationships, ambition, organisational politics and difficult decisions. The mentor can offer direct feedback and challenge assumptions without being drawn into established alliances or ways of working.
External mentoring can also cut through groupthink. Large organisations often develop shared assumptions about how things should be done. An external mentor can introduce practical ideas and fresh perspectives. This is access to someone’s professional track record: decades spent solving problems, leading teams, navigating change and learning what works.
Professional mentoring requires professional judgement
A professional mentor is not simply someone who has held a senior title. They need relevant experience, a credible record of delivery and the relevant personal qualities: patience, judgement, curiosity, empathy and the ability to listen.
Matching matters too. A structured mentoring programme can identify the mentee’s goals and offer a choice of mentors with the right combination of experience and personal fit.
At 10Eighty, mentors are interviewed and evaluated before joining the mentor team. A shortlist is then created around the mentee’s role, sector, experience and objectives, with the mentee involved in the final choice. This helps ensure both professional relevance and the right chemistry.
The relationship is led by the mentee. They decide what to explore, while the mentor draws on experience, suggests practical approaches, tests assumptions and opens up new perspectives. As trust develops, the agenda evolves with the person and the challenges they face.
Turning expertise into wider impact
Mentoring helps people use their knowledge and experience more effectively.
The skills that mentoring can provide include learning how to bring influence across departments, build an internal network, navigate an international organisation, delegate more effectively, and make better use of limited time. It can also develop the confidence to contribute at a more senior level, improve commercial judgement and gain support for a business idea.
The effects can spread beyond the individual. Someone who becomes more thoughtful about delegation, decision-making and working with difference brings those behaviours back into the team. They can become better at developing colleagues, sharing knowledge and creating space for different perspectives.
Mentoring can be particularly valuable after a merger, restructuring or difficult period of change. When colleagues have left and responsibilities have shifted, external support can help restore perspective, motivation and confidence. It also demonstrates that development remains a priority.
The return on investment
The cost of losing an experienced employee extends far beyond recruitment fees. It includes lost knowledge, disrupted relationships, reduced productivity and the time required for a replacement to become fully effective.
Professional mentoring can support retention, strengthen succession planning and help valued employees prepare for more complex roles. It also demonstrates to employees that their development is being taken seriously.
The organisations gaining most from mentoring do not treat it as an informal favour or an occasional conversation. They view it as a professional investment in capability, confidence and future leadership.
Your competitors are already making that investment. The question is whether your organisation can afford to leave that advantage to them.
