Passage Summary: An administrator argues that TAs aren't real employees because their primary motivation for working is to pay for their degrees.

Conclusion: Teaching assistants should not be classified as university employees entitled to benefits.

Reasoning: The only reason teaching assistants work is to fund their education, and they would not hold these positions if they weren't students or had other funding.

Analysis: The administrator is confusing the 'purpose' of a job with the 'status' of the worker. To weaken this, you need to find a way to show that why someone does a job doesn't change the fact that they are doing it. You might look for an answer that suggests other undisputed employees also work solely for a specific benefit, or one that points out that the actual duties performed by TAs are identical to those of recognized employees. The administrator's logic is a bit like saying a professional athlete isn't an employee because they only play to stay in shape.
