Executive management consists of folks who have been at the company 16+ years and it is starting to show in a negative way - lack of focus in terms of direction and vision, inability to commit to certain goals in a tangible way (e.g. put the resources against the products that have the most potential for growth and kill the ones that don't make money) and aversion to the types of calculated risks that will be necessary to avoid Morningstar from becoming another Value Line.
Many folks mention a 'flat hierarchy' and while that can be helpful, I think it's starting to work against the company. The people in the executive ranks have made their millions; the middle managers and their teams who are the ones cranking out all the work get paid below market wages but are expected to do the job of 3+ people. Burn out is common and if you're good at your job, the expectations keep getting higher.
No mentoring for managers and no career path development. HR is a disappointment - while the HR management claims to care about employees and the desire to be transparent, an initiative in 2012 to address salary concerns went no where and died after several months.
