I have a friend who has just been dismissed from their job after only 3 weeks. They were given 2 weeks pay as a notice period but they want to appeal. From what I understand they did something dangerous in front of the customer at the customers premises (think standing on top of balanced furniture to fit something rather than using a ladder). The customer complained to the company about unsafe practices and have said they don't want to use them again. However, friend has said that they didn't provide her with health and safety training or policy so they are being unreasonable to dismiss her. I didn't really know what to say. It's wrong that the company didn't provide the policy and they are definitely derelict in their duty but my friend is also very experienced and surely knows that this is generally just very unsafe behaviour without having to be told?
Does she have grounds for appeal or can they just sack her?
