What is the primary factor for promotion in Hannah's law firm?

In a law firm setting, the primary factor for promotion often hinges on experience practicing as a solicitor. This is because legal practice requires not only theoretical knowledge but also practical application and insight gained through hands-on experience. The more cases a solicitor handles, and the more challenges they overcome, the more they develop their skills and understanding of the law, making them valuable assets to the firm. Accumulated experience demonstrates a solicitor's ability to navigate complex legal situations, maintain client relationships, and achieve favorable outcomes.

While educational qualifications, networking within the firm, and performance ratings play significant roles in professional advancement, they typically supplement the fundamental requirement of practical legal experience. Educational background lays the groundwork, networking can create opportunities, and performance ratings reflect how well someone is meeting job expectations, but it is the actual practice that ultimately prepares solicitors for the responsibilities and challenges that come with higher positions in the firm.
