Yes, and I would agree with jno.
For more years than I can remember now, every year I’ve had an assessment of my PC workstation at work – including input from me. The output of the assessment is a short written report; some believe that the purpose of this assessment is to ensure my wellbeing at work – it is not, it ensures that I could not make a successful claim for repetitive strain injury (or similar) through my work activities.
If your employer has not conducted regular assessments of your work activity, including a risk assessment, and any reasonable steps they could take to mitigate injury – they are already on dodgy ground. Even without documentarily evidence of your complaints, I would bet the company would settle out of court.
But you might also considering finding alternative employment – suing them is unlikely to make you employee of the month, anytime soon.
