Pros
When I joined Jack in the Box, I found a culture that fostered learning and encouraged movement into other positions. I learned a number of different roles and found my work to be rewarding. My supervisors and managers seemed to want me to succeed, probably because it reflected positively on them. Of the 14 bosses I had during my tenure, I had positive relationships with most of them. This helped me feel valued as an employee.
Cons
The culture steadily declined during the last five years of my tenure. Instead of having supervisors and managers who lifted up and supported employees, I found my last five supervisors lacking experience and faking their way through each day, jealous of my tenure and the salary I had earned and overwhelmed with responsibility. I noticed a pattern of Jack in the Box laying off people regularly to appease shareholder pressure to reduce overhead because financial performance was not where it needed to be. Frequent lay offs made me and my closest coworkers fearful and anxious. I watched staffing shrink each year, expand the next only to be cut again. My advice is to learn what you can over a few years and move on to another company for advancement. The current wary culture advances employees based on favoritism.
