Answer:
Issue : Veronica's disability
Explanation:
The situation here is hiring Veronica or not due to her hardship. Something that can be considered is that there is no a clear standard on undue harship so this can be a useful weapon that helps as an argument against the opposing claim.
Besides it has got to be taken into account that an employer needs to make a reasonable accomodation for the employee, but this is not an acceptable reason for not hiring Veronica.
