The new law, which comes into effect in March 2005, means companies with more than 150 employees must comply with internal comms regulations.
However, 41 per cent of companies surveyed by the IPR had no dedicated internal comms staff.
The survey also revealed that 76 per cent of businesses knew little or nothing about the directive.
IPR director-general Colin Farrington said: ‘This is a wake-up call for PR practitioners involved in internal comms since some have less than a year to make their organisations compliant. They must now take the necessary steps to prepare for and implement change.’
IPR PA and education officer Gerald Chan said the directive could cause a strain on resources but heralded it as a way to strengthen comms between staff and management.
