When you start your job you will have a contract which will have details of how much notice either you or the employer has to give for you to stop working. It would be common to be on a months notice if you are on a monthly salary, although some jobs, such as ones for the government may require three months notice. If you are on a temporary contract then it is likely that you will be on a day’s notice and a person paid weekly probably needs to give a weeks notice.
