Former chief of Army David Morrison is the face of a new campaign to rid Australian offices of the word "guys", arguing that such terms exclude minority groups.

The Diversity Council of Australia campaign launched yesterday asks people to consider dropping phrases they have always thought "normal".

One such word is "guys", which is commonly used to refer to a group including men and women.

A campaign video shows a group of women cringing at being referred to as "girls", and a worker in a wheelchair questioning the use of the expression "walk the talk".

Mr Morrison, who is spearheading the #WordsAtWork campaign, said the use of inclusive language should be promoted.

"For some time I have been advocating that everyone in our society, from all genders, races, creeds, ages, disabilities, religions or sexual orientations, be given a chance to achieve their potential," he said in a statement.

"Unfortunately, in many workplaces, this isn't always the case. People use language to denigrate others and to take away their self-respect. Sometimes it happens unconsciously, but the effect is the same."

The new campaign was not about creating a "language police" but simply about encouraging people to use terms at work that were respectful, accurate, and relevant to everyone, he said.

"All the campaign is doing is saying, 'Look, it's a proven fact that more inclusive, more diverse workforces create real diversity of thinking and are more productive," he told the ABC.

"And one of the ways... that you can engender that type of environment is (by) being careful about how you speak to other people, talking to them with respect and listening to their views with respect."

Morrison admitted that "guys" was a word he had previously used.

"I have now removed that from my lexicon as best I can, I think it's important," he said.

But the idea of dropping the word "guys" provoked a storm on Twitter, with some questioning whether it would also lead to the loss of the traditional favourite "mate".
