Schwab's tight budget hiring model doesn't allow employees to focus on their strengths. There's an emphasis on everyone being generalists that can do everything and manage every aspect of given projects. Their thinking is that this helps them maintain a lean staff count. However, this "do more with less" strategy, causes a lot of burnout and lack of work-life balance.
Being a generalist is good when you are young and entry-level and unsure of what your focus is. But as you mature and specialize, not having your professional boundaries respected begins to take a toll on quality of life. Output also suffers, although Schwab may never know the difference due to their focus on keeping costs down above all other considerations.
