I honestly tried... Had a team of people with various skills,needs, and motivations. I not only encouraged to use the available opportunities within the business but also persuaded the CEO to invest in continuos training, heck, I even allocated time during work hours to do the learning at their own pace no questions asked. Nobody has gone beyond bare minimum,even when they had a chance to double their income in 2-3 years. So if people on relatively modest salaries won't do it,I don't know how else to push for it...
