Your company is trying you hard! Write your policy document, post each paragraph and someone will have a look.
In the meantime, does the Word processing program you are using have a spell and grammar check? If so, use it every time. Also, read through your work carefully before posting. You may pick up errors yourself - we all make typing mistakes.
NB English is always with a capital letter; the personal pronoun "I" is always a capital letter.
