Horrible management in the manufacturing department. Turnover in manufacturing leads to retention bonuses being unfairly distributed to employees on an arbitrary basis and management seems to have no problem with this. If you bring up bonuses to the management they will lie and tell you they are not aware of bonuses being given out and that you should focus on your own pay. Promotions are extremely hard to come by as the "cycles" are twice a year, and only two members of each shift/team can be promoted at each time. Director level management fabricated a rule that you must be in your position 1.75 years in order to be promoted, thus going against their own created job roles (one year of experience for associate III, two for senior associate I, etc.). This rule is wrought with irony when higher ups themselves are inexperienced and do not meet this rule. If you pride yourself on being a hard worker you will find yourself surrounded by free riders, which could be a good or bad thing depending on who you are.
