In a relationship, it is normal for partners to help each other with their jobs, such as providing advice or reading over written work.
However, it is not considered normal for a partner to ask their significant other to perform tasks that are essentially admin support or to complete their work for them.
There should be a boundary between work and personal life, and if the partner requires additional assistance, it should be addressed by their employer, not by the supportive partner.
Confidentiality concerns and potential ethical issues may arise when non-employees have access to confidential materials of a workplace.
