When I was hired they made a point of expressing how much they want everyone to succeed and that they were adamant and dedicated to helping you do just that. Right up until you encounter difficulty. Advice was vague, help was non-existent and the interaction with management at that time became very chilly.
They also appeared to have far more concern for the numbers, results that could be tallied by arithmetic. When asked to discuss program results, the number of attendees was always paramount. There was very little consideration for the value of the experiences that the patrons had.
It's also fairly telling that the turnover rate for the system is oddly high.
Libraries exist to serve the people of a community, not to serve their own interests by confusing attendance with quality.
Cons
Focus on Quantity over Quality, Very little support from management
