One of the contributory factors to DPI is our work environment.  Environmental factors can include: temperature (too cold or too warm), air movement (draughts or not enough ventilation), humidity, vibration, noise from machinery and lighting.  If you have a concern, you can talk to your manager, your colleagues or to your health and safety representative.  As an example of one thing we did in Access and Collections last year – Facilities Services visited our workroom to assess the ventilation problems we were having.  They then ordered and installed a different type of ceiling vent over desks where draughts were a particular problem.  In an open plan environment it can be hard to please everyone, but it never hurts to try and to involve everyone in the team in the discussion about options we could try that would be a good outcome for all.
