A little advice if possible..

[bav101]

In addition to carolines comments, get names of people who are ordering you to do unsuitable work, write a letter to the person who gave you the placement. Telling him your concerns and tell him you are happy to do any reasonable work, but you have taken advice and that says that the work is unsuitable for a psoriasis sufferer. Could he put in writing to you what you are expected to do.. So if things get bad health wise you would have evidence. Tell them in your letter  that you understand the idea of the placement system, but it should not be to the detriment of your health and you will turn your hand to anything reasonable, and will do this placement providing they will put in writing that it is not going to harm your health
Just another idea

I have a appointment at the job centre tomorrow, so i'll be hoping that my advisor is able to do anything, i know she tried to contact the company direct yesterday but the person she needed to talk to was unavailable or hiding, eating doughnuts or didn't want to talk to her. If I'm forced to go back i'll definitely be carrying out both of your suggestions.

Here's something that'll make you facepalm.. on the way out the door this afternoon this manager guy said.. "just so you're all aware, we will be wanting the gloves vest and boots back so we can pass them onto the next lot we get in, that goes for everyone with no exceptions"... he obviously never saw the state of my hands after an hour of picking crap up...

On a side note I've just tried to book a docs appointment, but due to the unique way they are overbooked There's nothing for mine closer than the 29th April. I'm also thinking of getting my knee's looked at, last couple of months they've been aching like a.. well pair of knee's that have been really painful.. thought it was just the cold weather, but today since its been warm same deal. so it wasn't the cold weather hehehe
