Sharon,

Good to see you haven't taken the 'knee jerk' reaction route!

Some information here

This affects certain individuals and not designed as a 'group therapy' fix!
My advice would be firstly have a system that records employees refusal of taking up night worker assessment as you have then fulfilled your duty.
Advice individuals to seek appropriate advice from their GP firstly.

Remember this is a medical condition and not a working condition!

Hope this helps

Lamps sold as SAD lamps tend to be pretty expensive due to their specialist casings / stands.

Look instead at Full Spectrum bulbs. These are low energy bulbs for standard lamp fittings (screw and bayonet) and provide a very high level of task lighting at a different colour temperature to normal bulbs.

I got one the other day from Amazon (look up Full Spectrum Light Bulbs) for £7.95. Just had a quick look and you can get a pack of 5 for £20.

Give them a trial and see what the staff think.

Well why not?
If you happen to work beneath a steel roof on the top storey of a 4 storey mezzanine floor warehouse with all the heat rising from below - you'd probably be glad of some iced water and cooling fans.

H&S is there to protect people but at the end of the day we also have to work alongside folks. If for the sake of £20 you can brighten someones day (or night), why not? Run a trial of standard lamps vs full spectrum lamps and check worker output and user feedback questionaires.
