I've been working for one employment agency on one of the construction sites at central London for several weeks. Today's morning me and another guy from the same agency came on site, changed our clothes and were ready to start working. The director of the construction company was very surprised to see us there today and he told us that we were not supposed to come today... he said that he had called our agency last week(!!) and told them that Friday would be our last day... The director didn't even know that we had been on site yesterday (on Monday), and he said that the company will not pay us for Monday. I called the agent straight away and asked him what was going on. He said it was his mistake(he said he phoned and texted us, but we have neither missed calles from him nor any text messages) and the agency will pay us for Monday. While composing this message I received a phone call from the agent. He told me that the payment for this Monday will be made this Friday together with the last week's wages. I didn't object to that, but I asked him if the agency was going to compensate me my today's travel expenses(£10), and he said NO... I believe that it is the agency who MUST compensate at least today's travel expenses to say nothing but the lost time since last Friday which I could spend searching for another job. I'm going to wait until my wages are into my bank account this Friday and then I'm planning to demand them to pay my travel expenses, but I need to know the correct way to do so. Could anyone please tell me what is the best way to claim that money from the agency? Thank you.
