Speaking up among work colleagues can feel uncomfortable.

• Seize the moment. Respond in a way that makes the speaker's assumptions clear.

• Discuss privately. Take the co-worker aside and gently explain what you find offensive.

"You know, I don't feel comfortable when you make these generalisations about Aboriginal people."

• Focus on the diversity of your colleagues.

• Tie tolerance to better performance. Diverse, flexible and respectful workplaces are productive and have a smaller turnover of staff.

• Refer to your workplace policies. Many workplaces have diversity policies and employee conduct codes. Refer to them if the need arises – not enough people use these documents.

Hints for speaking up to "Humourous" comments

It is unfortunate that in some instances a good laugh and a bit of humour in the office can turn sour when the speaker chooses to tell a 'joke' that is based on a racist stereotype.

• Don't laugh. Meet the inappropriate joke with silence or a raised eyebrow. Use your body language to communicate your view on the matter.

• Interrupt the laughter. Do not hesitate to interrupt the 'joke'. Explain how it feels prejudiced.

"Why do you think that's funny?"

• Set the limits. Letting people know that their behaviour is unacceptable will limit the spread of racist attitudes. You cannot control what other people say but you can set some boundaries. Just make sure that you follow through with them!

"Don't tell racist jokes in my presence anymore. If you do that again I am going to leave." OR "This workspace is not a place I expect to hear these sorts of remarks to be made. I can't control what you say outside of this space, but here I ask that you respect other people."

• Provide alternatives. Have a few jokes up your sleeve that don't rely on racial stereotypes or bias.
