GHG Bellfast, a shipyard company, employed a female welder. She was harassed by certain male employees. The men drew obscene graffiti directed at the victim all over the plant. They also made numerous suggestive and offensive remarks to the victim concerning her body. The victim complained about this atmosphere of harassment. The company’s supervisory personnel immediately transferred those male employees to another department with a warning. A few days later, she sued the company for creating a hostile working environment. Does GHG Bellfast have any defense against the charges?
