Hi there! She sounds stubborn! Keep dropping her at the computer until her behavior label says “Working on career.” When she successfully finishes her work cycle, drop her at the computer to work again. Do this over and over again until you see some progress in her progress bar. Every time she’s unsuccessful in completing a work cycle, have her start another one. A Workshop career magazine will not help her since she works in the Office.
You can also buy her a career change by tapping the “Upgrade Me” button on her details screen and scrolling to that option. The first few career options will also be office professions, but with enough career change purchases for her, kitchen and workshop careers (if you have a workshop built) will also be offered.
Good luck! Feel free to update us on her progress!
