I'd be interested to hear from any other social landlords with an in-house maintenance workforce (trades) as to what measures are taken to protect lone workers.

Currently we use an incident reporting procedure which informs an incident list compiled by our legal team. This annotates job orders that two persons are required, etc.

All staff are issued with a fuller copy of the official list as well as a mobile telephone and the option to request a second person should they feel the situation requires it.

All field based staff recieve fear of attack training.

Having worked here for 19 years I could count the number of incidents on one hand (easily).

We currently have a manager who is so risk adverse on this subject that I am struggling to explain that our control measures simply need to be proportionate to the risk. Am I wrong ??

It may help to also have a look at www.hse.gov.uk/violence/loneworkercase.htm where the HSE provide different case studies to see how some employers have tackled the issue. If their procedures are more in line with what you have already in place, this may assist your argument. It may even be the case that you might see something that others do that you may wish to do, although from your post I doubt that you need anything else.
