Is Please submit the report to Johanna or me correct grammar?

The grammar is technically correct, but it's not the most natural or polite way to phrase the request. Here's why:

* "Johanna or me" sounds awkward. It's more common to put yourself last in this kind of list.

* "Please submit the report to..." is a bit impersonal.

Here are some better ways to phrase the request:

* "Please submit the report to Johanna or to me." (This is the most grammatically correct option)

* "Please submit the report to Johanna or myself." (This is slightly more informal)

* "Please submit the report to either Johanna or me." (This is the most clear and concise option)

The best choice will depend on the specific context and your relationship with the person you're asking.
