There will be stress. Corporate Event Managers have the heavy responsibility of coordinating every aspect of complex happenings. Table cloths didn't arrive? Your job is to deal with it. The expert booked for Friday's employee training on sexual harassment has the stomach flu? Get out your employee handbook and get ready to train them yourself.
Why? Because, you are where the buck stops when it comes to pulling off these events, so you need to be ready to make sure they happen and happen well. So, yes, there's stress involved, but you seem to be just the person for the job. We can see it in your steely stare.
