Leadership expert Dan Rockwell says culture building helps to attract and retain the kind of people who will fulfill a company’s mission. He says some industries, such as banking, government and education, can be slower to change culture. He advises to start small, with a division, a team, or an office. And remember, a “great place to work” is often determined by what is tolerated on the job. For example, management allowing rudeness in a meeting, or allowing a great performer to break the rules.
