To me it is more like the ..For Sale VS 4 Sale just not the same effect with the 4 Sale
Same with ..Men Working VS Crew Working
When people approach a working environmental area extreme caution is in order & safety is number one thought, so the standard Men Working
sign reminds me of that fact.
A crew Working
sign surely will alert but to me a smaller job & risk.
Just my 2 cents sexist or not Safety is the number one emotion & alert is in order.
Also I do not believe women are this concerned about sexist language that has been a standard such as this, believe they are more concerned about the abuse they receive in daily life.
