What is an example of a neutral rule potentially leading to indirect discrimination?

Mandatory overtime for all employees can lead to indirect discrimination because, while the rule applies equally to all employees, it may disproportionately impact certain groups. For instance, this policy could unintentionally affect those with caregiving responsibilities, such as women, who are often the primary caregivers in families. If mandatory overtime creates a barrier for these employees to fulfill both work and personal obligations, it could result in a discriminatory effect, even if there was no intent to discriminate.

In contrast, options such as flexible work hours for specific departments or a strict dress code might cater to specific needs or circumstances without negatively impacting any particular group, while non-variable job training requirements, assuming they are consistent with industry standards, also wouldn't typically create a discriminatory effect. The key aspect of indirect discrimination is that a seemingly neutral rule can lead to adverse effects on a particular group, which is precisely what happens with mandatory overtime in this context.
