I interviewed over 60 employees of Far East Trade Development Company in the last six months and consulted with health experts in eye and wrist fatigue. 1 also reviewed all the current literature available for computer health hazards (危险).
My recommendations are as follows:

3. Employees need adjustable chairs which can give their backs a stronger support.
For the technical possibility of designing the anti-radiation screens, you may consult Mr. Joseph Miller, and for the specific application of wrist-support devices, you may consult Mr. Benjamin Stone, Technical Department. If you have any other questions or would like to discuss my recommendations, please let me know.
