Asking for a friend, she is currently on a small contract (7 hours) in a supermarket.
She has secured another job WFH of around anything between 16-48 hours a week. (The job allows her to book her own hours in for the weeks ahead around commitments).
However, as the supermarket job is permanent and this other job is “temporary but ongoing” she would like to remain in the supermarket as well. Obviously she will have no P45 to give to her new employer so what does she need to do about being taxed?
Thanks In advance for any help.
