Workplace discrimination is something that employers generally go to great lengths to avoid. There may be no intent to violate the rights of any particular person or group, but employees can still experience discrimination and they have the right to take legal action.
However, employers have the right to defend against these claims. Defending against these claims can be a fairly sensitive process, as it requires employers to explain employment decisions without minimizing the issue of discrimination. In many cases, news about alleged discrimination is biased against an employer so responding to the claim can be tricky situation.
