How replaceable is that person?

If they are a normal business admin they are very replaceable. So you don't have to make life easy for them unless they can justify the cost of doing so.

How busy are they?

If you have a 1 EFT position filled by an administrator that is only 60% busy then there is no cost in slowing them down until they're at 100% capacity. Then you might think about making life easier for them to avoid having to hire the next administrator. If people avoid doing their job because they don't like their tools that is a disciplinary matter. Time to find an administrator that can do the job required.
