Pros
Consistently paid bonuses, good overall corporate strategy with consistent growth that is likely to continue. There are some good people here who really care, but many are looking to get out. If you're lucky enough to not be in Dallas, you're isolated from some of the micromanagement.
Cons
Employees are not trusted. Everyone is replaceable. Telecommuting is not allowed (in the operations division, and from what I hear in others as well). You are expected to work at least 9 hours a day (CEO wants 10). Expect to be judged on metrics and SLAs that have nothing to do with actual job performance. You are expected to log time to the minute. You will use ancient software tools that are buggy, difficult to use, and not updated simply because management wants the metrics they generate. If you're looking to be a real project manager, a PM job at Securus is not the job for you. You will be micro-managed by supervisors and managers with no project management experience. Any change to your projects (even simply pushing out a milestone date that doesn't affect the complete date) will require supervisor approval. If you're OK with simply ordering hardware, checking some boxes, and hosting a few meetings for your job, then maybe you'll enjoy this. Compensation is very poor. The project manager salaries at Securus are ~30% below the nationwide average. The bonus helps, but not much. They get what they pay for... if Securus hired (and actually cared about keeping) competent project managers, they would need half the PM staff.
