I've been signing on since about last November. Some of the people in my jobcentre are lovely, and really helpful, but some are definitely not. For the first few weeks I had a different advisor each time and most if these didn't bother to do a jobs search. They simply said, "Have your circumstances changed at all? Sign here. See you in 2 weeks' time." Once, I asked the girl if she was meant to do a jobs search for me (even though I do them myself all the time too) and she said they didn't have time and didn't do them for people. Hmm, ok, I thought they were meant to offer advice but ok. Then the next week I had a lovely man who did do a jobs search, and when I expressed my surprise he said the girl had been talking nonsense and they were meant to do them. So I'm not sure whether they're meant to do them or not, as they very rarely do for me. Last time I was there for all of thirty seconds and the girl was chewing gum throughout, which I didn't think was very professional.
I also get occasional short term work, so if this happens I have to ring up to sign off, then on again when the work stops. If I phone the wrong number they can't put me through to the right people even though it's in their company. I have to ring off and dial the number they've just given me. I once said that I thought it was a bit daft that they couldn't connect me to the right place, as it was within their company, and was told "oh well, I suppose I could try, but I don't think it will work." She tried, and it did work, so it is possible but they don't want to bother.
When I have signed on again after 3 days work or whatever, a couple of times it was quite easy but once I had to answer question after question, for about half an hour, over the phone. I tried to say I never normally had to do this, but he was adamant. When I went into the job centre for my first appointment after that I was told that no, it hadn't been necessary.
I am pretty sure that after you have signed on for a certain amount of time, things happen, you get a more detailed interview each time, etc. But, every time I sign off and on again it counts as the start of a new claim, so I never get to the time when you're given more help with finding a job.
