When can gender be a bona fide occupational requirement for the job?

Gender can be considered a bona fide occupational requirement (BFOQ) when it is essential for the job's performance and is reasonably necessary for the operation of the business. This typically applies in specific contexts, such as roles involving personal privacy or authenticity, like acting or modeling, where a particular gender may be crucial to the job's nature. However, such cases are rare and must meet strict legal standards to ensure they are not used to justify discrimination.
