Pros
Incredible staff to learn from. I grew a lot from other staff members personally and professionally with the majority of their attitudes and perspectives on problem solving. There were a lot of staff who genuinely cared about helping the community.
Cons
More bureaucratic than smaller library systems. A lot of policies from the top administrative team (COO, CEO, CFO etc.) that were very disconnected from the daily tasks and made the work more stressful than necessary. Plus we were asked to do things far outside our job descriptions that left a lot of employees voicing they felt taken advantage of, including me. Expectations on handling security incidents was one example.
