Quentin needs a wheelchair to be mobile. His department manager, Ronnie, thinks

he is a good worker but refuses to install ramps in a section of the department store where they work. This means that there are parts of the store that Quentin cannot access, and some types of work that he cannot gain experience in.

Whose responsibility is it to ensure Quentin can get to all parts of the store?

Is additional experience part of Quentin's workplace rights?
