Final answer:
The "rule" Angie broke was not maintaining a professional tone, discretion, and proper judgment in the workplace when she compromised investigations and falsely claimed to be an agent on social media. Additionally, improper handling of email communication by others led to sharing private discussions without consent, which is also a breach of professional etiquette.
Step-by-step explanation:
The "rule" that the deaf woman Angie broke in her email to her supervisor was related to professional communication and discretion in the workplace. This rule, often unspoken but commonly understood, involves maintaining a professional tone in communications and being careful with sharing sensitive information, especially in written form that can easily be forwarded. Angie compromised undercover investigations, claimed to be an agent, and shared personal information that could potentially damage professional credibility. These actions collectively indicate a lack of judgment and discretion, which are crucial in intelligence and law enforcement fields.
Email correspondence is intended to be private between the sender and the recipient. In the given scenario, forwarding an email without consent—especially one containing unprofessional language—violates the ethical standards and trust within professional communication. The attorney's email, though intended to be confidential advice, ended up being shared without his permission, causing distress due to his own unprofessional language. Additionally, using all capital letters in emails is considered shouting and is not appropriate in professional correspondence. Lastly, extensive explanations or nuanced discussions should preferably be conducted in person or over the phone rather than in lengthy emails to better convey tone and prevent misunderstandings.
