Thanks to all for the answers (and for any other info / opinions)
Yes, we do indeed HAVE to sit in front of those 60Hz refresh rate screens at LACC Swanwick, and yes headaches are a problem.
Several points here:
1) No one knows the long term effects of exposure to "flicker". I can't imagine that it is good though.
2) Other, better, systems are available right now. Which make the "NATS Spokesman" either ill informed, or less than economical with the truth. He should be made to answer for his errors, deliberate or otherwise.
3) Despite what it says, and is required by law to do, NATS is not "ensuring the well being of its employees". Replacement of the screens in use at LACC Swanwick must be done as a matter of urgency .
It seems to me that the small matter of my, and my colleagues, health, is being IGNORED by NATS, possibly on cost grounds. How much is our long term health worth?
NATS Knows there is a problem. Can anyone tell me what it is doing about it? Internal communications are DIRE as is common knowledge.
