How does one deal with workplace discrimination?

Wow, that is a loaded question. If you are the employee being discriminated against, it might be time to stand up for yourself. However I think, is only worth the effort if you have the support of HR and the higher ups who know what's happening and are prepared to step in and do what it takes to help you blossom and work within a dignified setting in that company. If not, get your CV ready. That's why it is so important to have a solid HR team run by a determined and principled person.

• Recognize the difference between job level and job title. An employee may be granted a particular title, but if the level of responsibility and challenges haven't changed, the worker can feel he is being appeased and that he isn't fully trusted or valued within the organization.
• Examine barriers to both entry and advancement.
• Study companies that consistently do things right. Pay attention to diversity leaders, and integrate their best practices into your workplace culture.
• Concentrate on targeted recruitment strategies.
• Create focused employee-development initiatives such as formal mentorship programs that equalize resources and facilitate diversity.
• Form affinity or diversity groups within the company
