Ideally, when you apply for a job you should provide the employer with a cover letter and a resume.
A cover letter is and must be specific to the job you are applying for. If you are applying to work in a cafe your cover letter should address why you would be the best person for the position. Your reason and examples of experience should therefore relate to working in a cafe. If you were applying for a job as a garden assistant, your reasons and experience should relate to working outdoors in a garden.
Your resume stays the same but must be updated when you have something new to add.
No matter how you set up your resume and cover letter, be sure to look at the link below and make sure you include everything listed in your work.
