The word shafting is often used to describe being treated unfairly or in a negative way and so the general manager shafting the speaker would make them resentful instead of feeling joyful.
Context: "I got shafted by my general manager at my job."
Hypothesis: I feel completely joyful that my general manager would do something like shafting to me
Based on the context, is the hypothesis true, false, or unknown?
