Management continues to make the same mistakes and continues to react without forethought. The owner refuses to relinquish responsibility and tries to do it all himself. No real management structure. No room for advancement; they have no organizational structure so your job title is essentially meaningless. Training is fully self guided with no mentoring or assistance; "Sink or Swim" mentality.
Don't give notice! They have and will terminate you immediately without compensating you for the additional weeks you would have worked had you not given notice.
