Final answer:
For HR service requests, using an employee's First Name and Last Name is most practical for identification. Other details like Employee ID, Date of Birth, Email, or Phone Number might not be necessary or could be sensitive. In formal communication such as a cover letter, addressing the recipient correctly is key to professionalism.
Step-by-step explanation:
When documenting the employee who requested HR services, the most practical fields to use would likely be b) First Name and Last Name. These identifiers are easy to record and provide a clear reference to the specific individual making the request. While options like Employee ID are also specific, they do not convey immediate recognition for the person processing the request without additional steps to look up the ID. Moreover, personal information such as Date of Birth or contact information like Email Address and Phone Number is not required for simply identifying who made the request, and might be protected depending on privacy policies or local regulations. Further, using Department and Job Title alone could be ambiguous when multiple people in the same department share a job title.
When addressing a formal letter, such as a cover letter to a hiring committee, it is important to use a professional salutation. If the name of the contact person is known, the letter should start with "Dear Mr./Mrs./Ms./Dr. (Contact's Last Name):". If the contact person's name is not available, one should address the letter to "Dear Hiring Committee:" to remain formal and professional.
