Tech management is deeply unprofessional from the top down. Some due to being poorly trained first timers, others due to being long timers surrounded by yes men. VPs and directors will unprofessionally badmouth their peers and mid management to low level employees who they are friendly with. Racist comments and actions are ignored by HR. Healthy work life balance is actually discouraged.
Certain members of upper management have openly said they like it when people get divorced so they work more, and they don't want female employees to have kids. They use offensive nicknames for many of the employees and openly joke about them performing oral sex on a specific member upper management. Neither local nor Chicago HR are helpful and anything you discuss with them will be used by your manager against you.
If you're interviewing for tech here ask how many tech employees have left in Q1 2017.
