The survey, conducted by computer image detection specialist PixAlert in the conjunction with the Chartered Institute of Personnel and Development (CIPD), has also shown that 54% of senior managers questioned were unaware of their personal liability for illegal and inappropriate images in the workplace.
CIPD also claims that 66% of companies surveyed have an out of date "Computer Acceptable Usage Policy" for the management of inappropriate and illegal images.
A majority of the respondents – HR and IT executives at over 200 medium to large-sized UK organisations from both the public and private sectors – said they have some technology in place to provide a degree of protection to prevent illegal and inappropriate images getting on to the corporate network via the web or e-mail.
However, 68% have not installed technology capable of identifying improper images, which can enter through desktop or laptop computers on, for example, memory sticks, CDs, DVDs and camera phones.
"In a climate where the obligations for corporate governance are increasing, the survey highlights that a high number of companies and their directors are exposed to the risks and potential liabilities from illegal and inappropriate images in the workplace," said Dave McLoughlin, Director of PixAlert. "Companies need to tackle this sensitive issue with a combination of good policies and procedures and the deployment of suitable technology."
Imogen Haslam, CIPD Professional Adviser, said:
"Many people may view some inappropriate computer images as a bit of harmless fun. But this is not just about sparing blushes. A culture where some dodgy pictures are tolerated can all too easily create the environment where far more offensive or even illegal images can find their way into an organisation – by accident or otherwise."
Haslam continued:
"Employers need to have clear, consistent policies that leave no room for doubt in the minds of employees. A little tolerance could cause a lot of trouble later."
"HR needs to work closely with IT to make sure that the systems are in place to monitor and enforce policies. But ultimately bosses who want to be sure they are protected from prosecution resulting from illegal images stored on their systems need to get the people management policies right."
