Swing shift, period. Advancement is not based on your work ethic, but rather how well you interview. Filling in for a position does not help you get better position, they will hire based of politics, nepotism, etc. Paperwork is the stated king(what gets you in trouble) when production numbers are really all they care about. Hiring people with no experience in leadership is maintained by the good operators who make them look good. Often packaging troubleshooting and maintenance problems go undealt with due to lack of experience. Hire based on paper (degree) not from within.
