The power of a corporate events manager comes in the form of control. These events—trainings, seminars, meetings, parties, even the occasional ballgame—are important to the corporations that host them. Businesses don't tend to throw money away on unimportant things, so you need to constantly prove why you're important enough to have money thrown at you.
And that's where the power comes in: you'll be in control of the planning and execution of these events. Whether they're smashing successes or resounding duds depends a lot on how you set them up—and ultimately decides whether you make your clients happy or sad.
When it comes to the events themselves, there's no one more powerful than you. The executives may be paying for everything, but the whole reason they hired you is that they don't want to know what they're paying for.
The power of these events grows with the number of clients you have. You'll have the power to determine what the head of Company A eats for dinner. You control the decorations for the annual Halloween party (pumpkins everywhere) for Company B. Meanwhile, Company C is on the week-long team building retreat you organized to Paris.
No, not that one; we mean Paris, Texas. You're still constrained by your event budget. That's something the bosses will definitely be paying attention to.
