I think one potential way to improve the culture at the company would be to return some amount of decision-making power back to managers and VPs, particularly around people-focused decisions and policies.
I know that in my particular unit within Fiserv, my direct manager, their manager, and our SVP were all fantastic people who genuinely cared about their employees and wanted to give them more leeway and freedom. However, due to the C-suite ruling with a heavy hand—dictating every little detail and micromanaging from above—my unit's managers and leaders were mostly powerless to improve the quality of life for their employees. I think a simple way to improve employee satisfaction and morale, at least for units with good managers, would be to let them self-govern with regards to things like WFH/RTO policies, working methodologies, etc. No one knows a team's needs better than the manager of each team, so it makes little sense for the CEO to be dictating policies around the day-to-day minutiae of employees' work lives. Such decisions would be better left to managers, who are ostensibly there for exactly that purpose.
@mzp+1kvJnvNw makes an excellent point.
