The Field Guide to Frontline Care

Some of the hardest parts of frontline work are rarely taught. How do you hold a boundary without punishing someone? Respond to anger without escalating it? Stay compassionate without becoming overinvested? Keep showing up without hardening?

The Field Guide offers practical tools for the moments that don’t make it into training manuals or case conferences.

Inside you’ll find short, shift-tested chapters on communication, boundaries, conflict, grief and sustainable frontline practice. Built for real encounters. Written for the work as it actually happens.

Published by Ethica Press. 138 pages, paperback and ebook. Available on Amazon and from your local bookseller.

Reader reviews

What readers say

Reviews and comments from people who have read The Field Guide.

Just got my copy and plan to get more so my whole team can each have one, and want to make it part of onboarding. Been looking for something like this that is practical and aligns with our values.

The short reminders about where to focus your attention and how to approach an encounter are the kind of things I could imagine reviewing before or during a shift.
Dr. Rita McCracken, Amazon review, 5 stars
I bought extras and have gifted them to our supervised consumption site, frontline outreach, some of our nurses working in wound care and primary care, social workers and nurse practitioners!

I’ve been telling all of my colleagues to buy it. I’ve brought my copy to work every day this week.

If I could I’d come into work and pull an Oprah style “you get a book! And you get a book!” moment.

For libraries

For library staff and library members

Library staff meet people living with homelessness, substance use and distress every day, often with little training for it. The chapters on refusal, de-escalating language and boundaries apply directly to that work.

Use it for staff training

Chapters are short enough to read before a shift, and each ends with a quick reference and on-shift reminders a team can discuss together. Libraries can order copies for staff at the bulk price, or book a training session with Marcus.

Request it for your library’s collection

Most public libraries let members suggest a title for purchase. Look for “Suggest a purchase” on your library’s website and give them these details.
