ENVY: Thou shall not focus on advantage of youth, but concentrate on furthering career development. As the demographic changes in the workplace, many senior staff feel like outsiders, Jackson says. When senior staff members feel unwanted and invaluable, they usually become disengaged and ultimately resign or are asked to leave. Rather than quitting, Jackson suggests channeling your skills and experience into opportunities for professional growth. Seek to learn from younger counterparts while also teaching them from your own experiences. Jackson also encourages senior professionals to remain contemporary, constantly learning and sharing.more
