Which topic is considered unlawful to inquire about during an interview?

Inquiring about childcare arrangements during an interview can be considered unlawful because it may lead to potential discrimination against candidates based on their parental or caregiving status. This type of question could suggest biases against individuals who have children, particularly women, and can unintentionally perpetuate stereotypes about a candidate's commitment or ability to perform their job.

Employers should focus on assessing a candidate's qualifications, experience, and availability for the position rather than personal circumstances that are not directly related to job performance. Topics like professional references, previous work experience, and availability for shifts are directly relevant to a candidate's ability to fulfill the job requirements and do not pose the same legal or ethical concerns associated with inquiring about childcare arrangements.
