The word "workmanlike" and phrase "workmanlike manner" appear frequently in contract terms, but are obviously gendered. For example:
The services will be performed in a professional and workmanlike manner.
Is there a gender-neutral term that is a suitable substitute?
To clarify, by "suitable", I'm looking for indication that a proposed substitute would be understood to carry the same meaning in the context of a contract. Synonym-search does not answer that.
