Employers are making more effort to meet staff needs, according to joint research by SHRM and eePulse.
Six out of 10 organisations now offer staff an open door policy with management to discuss concerns, and allow staff to postpone or cancel business travel.
A third are establishing a task force to examine safety and security issues and a fifth are providing diversity training to improve awareness of ethnicity and race issues due to terrorist attacks, claims the research.
However, only half of American employers are planning to commemorate September 11. The survey of 7,466 HR professionals shows that while a third will observe a moment of silence, 45 per cent will not mark it.
It finds companies underestimated the impact of the terrorist attack. More than 70 per cent of US firms initially claimed they were prepared to return to 'business as usual', but in reality only 41 per cent have been unaffected, according to last month's survey.
"Regardless of geographic location, respondents cited ways that relationships between people at work changed since September 11," said Dr Theresa Welbourne, CEO of eePulse. "Some respondents said their employees were more caring; others said employees were more focused on family and friends, and another group indicated an overall sense of loss that resulted from 9/11, the anthrax scare, and the overall downturn in the economy."
The survey also finds that employee relationships have changed in the wake of September 11 - respondents said many colleagues are now more caring and employees are more focused on family and friends.
