With over 1.3 billion English speakers worldwide conducting business every day, mastering business English is no longer optional — it is a fundamental skill. Whether you work in a multinational corporation or a growing startup, the ability to communicate clearly in English determines how effectively you collaborate, lead, and grow professionally.

What roles and areas exist within an organization?

Every company has a structure, and understanding the vocabulary behind it is essential for professional communication. One of the most important terms to know is C-suite (also called C-level), which refers to the highest level of management within an organization [0:27]. This category includes titles such as:

• CEO — Chief Executive Officer, the top decision-maker.
• COO — Chief Operating Officer, responsible for daily operations.
• CTO — Chief Technology Officer, who leads the technology strategy.

Knowing these titles and their responsibilities helps you understand how organizations function and how to address the right people when communicating across departments.

Why are phrasal verbs so important in business English?

Phrasal verbs are combinations of a verb and a preposition or adverb that create a meaning different from the original verb. They are extremely common in the business world [0:44], and not knowing them can cause confusion during meetings, emails, or casual conversations with colleagues. Some key examples include:

• Catch up — to get updated on recent events or progress.
• Circle back — to return to a topic or follow up later.
• Put off — to postpone or delay something.
• Call off — to cancel a meeting, event, or plan.

These expressions appear constantly in everyday workplace interactions, so recognizing and using them naturally will make your communication sound more fluent and professional.

How do cultural differences affect business communication?

Effective communication goes beyond grammar and vocabulary. Understanding the difference between high-context cultures and low-context cultures [1:05] is critical when working with international teams.

What is a high-context culture?

In high-context cultures, people share a lot of background information and rely on context, assumptions, and inference. Communication tends to be indirect, meaning the listener is expected to read between the lines rather than receive explicit instructions.

What is a low-context culture?

On the other hand, low-context cultures favor direct communication [1:16]. Messages are clear, explicit, and leave little room for interpretation. There is nothing to infer or assume because everything is stated openly.

Recognizing which style your colleagues or clients prefer allows you to adapt your tone in both emails and spoken English, avoiding misunderstandings and building stronger professional relationships.

What will the final project look like?

At the end of the course, you will design a practical project that brings together everything you have learned [1:26]. This project involves:

• Creating and sharing the organization chart of your company using the vocabulary covered throughout the course.
• Discussing time zones and how your team members coordinate meetings across different regions.
• Reflecting on whether you have used inclusive language in your workplace.

Once completed, you will share your project with other students, creating an opportunity to practice real-world business English in a collaborative environment.

The course is led by Jess Harris, dean of Platz English Academy and an English teacher with experience dating back to before 2012 [2:00]. With over six years in academic management, she brings both teaching expertise and firsthand workplace knowledge to every lesson.
