Because I write for so many different industries and environments, I have numerous grammar and style books on the shelf.
Why? Every environment requires a slightly different approach to language usage, and each arena differs in terms of what is considered acceptable or not acceptable.
Without exception, the first resource I turn to is Action Grammar, by Joanne Feierman.
One of the most practical grammar books on the market, it's clear, it's direct, and it's easy to use. It focuses on real-world issues relevant to business communications.
And, unlike more stodgy sources, she agrees with Winston Spencer Churchill (and me) that sometimes it's ok to end a sentence with a preposition.
So, if you want one trusty resource to help your on-the-job writing stay crisp, clean and accurate, grab Action Grammar and go.
