Passage Summary: The company's rules for firing people are so blurry that a boss could easily fire someone just for having different opinions and claim it was for 'bad performance.'

Conclusion: Vague workplace regulations might lead to employees being fired for personal disagreements with their bosses.

Reasoning: The current rules for dismissal are poorly defined, specifically failing to explain what counts as 'unsatisfactory performance.'

Analysis: Sarah is worried that a lack of clear definitions creates a loophole for abuse. To justify her reasoning, we need a principle that connects vague standards to the likelihood of arbitrary or unfair application. The argument assumes that when a term like 'unsatisfactory' is left open to interpretation, the person doing the interpreting will use that power to target people they simply don't like. You should look for a generalization that suggests vague rules essentially invite subjective or biased enforcement.
