further to all the other learned replies i would like to add. what does it say in your contract ?? most likely you are working under a terms of engagement,and are not an employee... for tax purposes you are certainly not an employee,though the agency MUST deduct paye...and your contract will expressly have to say if you can claim anything from the agency...which i very very much doubt. yes, you can try and go self-employed...but in the main, an agency wont entertain you as this has a knock-on affect to their terms and conditions with the client..and going directly to the company re self-employed at morrisons ?...not going to happen either, they need the numbers and flexibility that an agency provides.. you are no worse off than a regular employee, so chin up !
