While traditional, one-on-one mentorship programs have long been the gold standard, today’s professionals are tailoring them to fit their unique career goals. Successful mentorships can be career-defining and life-changing. Paired with a good mentor, mentees can learn the ins and outs of their chosen field, expand their professional networks and accelerate their career growth. According to a survey by the American Society for Training and Development, a full 75 percent of executives say mentoring has been critical to their career development. A CNBC/SurveyMonkey Workplace Happiness Survey found that more than 90 percent of workers who have a mentor say they’re satisfied with their jobs, including more than half (57 percent) who say they are “very satisfied.” To meet the professional goals of today’s diverse workforce, many mentorship programs are tailored to benefit specific groups of people, including people of color, first-generation college graduates, women business owners and women in traditionally male-dominated fields. Businesses win, too. Many companies that have made an investment in quality mentoring programs have found that they help retain valuable employees.
