Dear [Manager function and name],
I am writing to you because I would like to apply for a job in your [Job location]. I have shelf filling experience in my local newspaper shop but I need something more suitable and regular due to me starting my family soon. My responsibilities were to refill the shelves and to make sure of any deliveries so that there was someone who knows what the shop needed. I live very close to the supermarket so I am able to walk and I am able to get there in minutes if you need someone to cover someone else’s shift quickly. I am a hard worker very determined to show people what I can do and prove myself.

I can work anytime for however long. You will find attached my full CV with all of my contact details. If you have any questions or want to talk with me don’t hesitate to call. I hope that you will consider me and I look forward to hearing back from you.

Yours sincerely

[Your name]
