Intern vs. Employee: Whose Job is Harder?

You might think there is an obvious answer to this question and wonder why I'm bringing it to debate at all.  It seems like a no brainer, why would a part-time (or even full-time) intern have a harder job than someone actually employed by the company?

Let's break it down:

Employee

• 40 hour work week (but let's be real, in PR we all know it's more)
• Multiple clients, projects, meetings, etc.
• Work-life balance challenges
• Inter-company relationship maintenance

Intern

• Busy work 
• Smaller tasks
• Part-time (generally)
• School-work-life balance

The biggest difference between the intern and the employee is that the job isn't the intern's end-all. They aren't bound to this company for an extended amount of time like an employee is. However, the employee is there every day. They're familiar with the in's and out's of the people they work with and the clients they have.

I think it's harder being the intern because you're NOT there every day. Even if you are, you're not included in every email chain and every meeting. It's hard to get completely familiarized with every client to the proper extent when the job isn't your main focus because of school, extra curricular activities, etc.

Which do you think is more difficult? Have you had an experience where you struggled as an intern but felt that if you were employed you would succeed?
