Frontier's longtime CTO is a huge part of the problem faced by the company.
He's a micro manager who does not communicate, he does not build teams, he does not invest in talent. He empowers the wrong people and is solely interested in securing and defending his kingdom. Scores of critical decisions that need to be made quickly get stuck at his desk, or at the desks of his direct reports, who are not empowered to decide things themselves.
His decisions are shaky, his leadership is abysmal. He and a few of his handpicked bad lieutenants brought you the botched April 2016 cutover. It took an army of dedicated and bright team members to manually patch the myriad holes caused by terrible leadership and execution.
His scorched earth approach is legendary, HR won't touch him, they are terrified of him, even when an employee steps forward with solid evidence of some malfeasance. Say buh-bye to that whistleblower, as soon as a plausible opportunity presents itself.
The workplace culture that he's created has had a corrosive effect on morale. He's bullied and dominated his peers and his direct reports to the point that his org has a bizarrely wide scope of control that they should not. And his approach is responsible for a steady and voluntary brain drain where talented tech staff have left, or his weaker peers have jumped out or have been discarded.
None of this is a secret, anybody internal with eyes and ears open knows that much of the dysfunction comes from IT. It is time for a fresh start and time for a new perspective from an outside hire.
