My company insists on expiring passwords every 28 days, and prevents reuse of the last 24 passwords. Passwords must be 14+ characters long, with forced minimum complexity requirements. All systems automatically lock or logout after 10 minutes of inactivity, so users are forced to type in their credentials frequently throughout the day.
Yes people suck with creating decent credentials, but it's the company's security policies breeding that behavior.
Was told it wouldn't be allowed because you couldn't restrict it using GPO... Until I told them they could absolutely apply those restrictions using GPO and even provided the ADMX templates.
