The way mentoring programme design was approached ten years ago needs to be reconsidered in the light of more recent generational differences in the workforce. By 2020 half the working population globally will come from the generation born between 1980 and 2000. As generations evolve, so do the methods for training, developing, coaching and mentoring people. Mentoring someone from the Millennial Generation (sometimes known as Generation Y) is not textbook developmental mentoring as we have experienced it previously. Understanding Millennials’ quite different career and value expectations is key if mentors are going to provide the right type of support to them, as well as the form of mentoring that Millennials relate best to, in order for organisational mentoring programmes to be effective.
