Dd who is 21 answered an ad for a job in a cafe/restaurant. She worked 16 hours then when she texted for confirmation of hours the following week was told that a customer had complained and she was not to return. This is unlikely. She is experienced in the work and had tips from most customers. It is a new business though and the food was a long time coming. In any event it is more likely that they realised they couldn't afford wages. Dd had confirmation by text that she would be paid for the work she had done.she has not been paid.
I assume that dd needs to write to the owner formally asking for her wages. Then issue a claim against her. There is no written contract so I assume she can claim minimum wage.can she also claim for notice?
