Final answer:
Not all questions related to boss treatment and compensation are necessary when suspecting workplace bullying.
Step-by-step explanation:
When suspecting workplace bullying, there are several questions that you need to ask to gather information about the situation. However, one question among the options provided that is not necessary to ask is:
a. Is your boss treating you well and compensating you adequately?
While important, this question is not directly related to workplace bullying. The other options, such as asking about impossible tasks without training, surprise meetings, social isolation, and interference, are more relevant in identifying potential instances of workplace bullying.
