Thomas Hancock has been the administrator of the clinical laboratories of a large urban hospital for many years. He excels at fiscal management and he has been successful in acquiring a state-of-the-art laboratory information system to increase efficiency in the laboratories. However, he is reluctant to hold department meetings or provide feedback to staff. Staff evaluations are seldom completed and his department team is unmotivated. Mr. Hancock primarily communicates to his staff through memos. All processes must be handled according to his rules and he is unwilling to accept input from others. No one is allowed to make decisions on their own (no matter how small). When a staff member does something Mr. Hancock does not like he sends a memo to everyone pointing out the problem and how it should have been handled.

Can you guys help me on this? Thank you! Here is the question: Is it possible for a country's economy to be based entirely on services? Here's my classmate's reply: It is technically achievable but difficult for a nation's economy to be completely focused on services. Services are becoming the main economic sector in modern economies, particularly in high-income nations. For instance, services make up more than 75% of GDP in the US and the UK (World Bank, 2020). This covers industries like technology, finance, healthcare, education, and tourism. Rather than manufacturing or agriculture, human capital and knowledge-intensive industries are the main priorities of a service-based economy. A solely service-driven economy would, however, have serious difficulties with regard to trade imbalances, resource availability, and independence. The fact that services by themselves do not produce tangible things is one of the main challenges. Basic necessities for a nation still include food,…
While working as a new employee at the Defense Contracting Audit Agency, you noticed that a fellow employee was studying intensely for the Financial Accounting section of the CPA test. You planned to sit for that test section in two months, and your colleague was sitting for that test section next Thursday. On Thursday evening, you phoned your friend to see how she was doing after the test. She thanked you for being considerate and told you that she was emotionally drained. Nonetheless, she then kept you on the phone for 15 minutes, telling you about the “nasty” Statement of Cash Flows and Consolidation problems she encountered. What is the ethical issue? Did either of you commit a discreditable act under the Code of Conduct?

You recently represented your organization at a career fair held at a college campus in Toronto. A number of students submitted their resumes to you, in hopes of securing employment upon graduation. A few students submitted resumes that were very impressive; however, when you spoke with each of them, it became apparent that they had embellished or "padded" their resumes. The students had misrepresented their skills or experience in order to make themselves appear more qualified. Now back at your office, you must make a decision as to whether the conduct of these students should disqualify them from employment with your organization. What four questions would you have to ask In order to determine whether the students' actions conform to the categorical imperative? Is it ethical for someone to pad their resume? Why or why not?
