Starting to Find Light:
A Reflection of Knowledge Gathering Efforts on
Indigenous People in Our Profession

I
    have to admit, I didn’t realize how much I didn’t know.
    Please be kind as I stumble to find the right words and if
    I approach sensitive subjects in an awkward way. Think
of me as reaching my hand out to you for support. It is only
through your experience and knowledge that I will truly
comprehend the intricacies of our nation’s indigenous story –
past and present.
   This is my story of the first steps taken to understand the
landscape and I hope it helps others who are standing in the
shadows. I am far from knowing it all, but am are willing to
learn and support the Canadian government’s call to help
others grasp the situation with greater conviction.1
   I had heard news broadcasters talk about the struggles of
indigenous communities over the years and recognized the
diagnostic and testing connection to our profession – greater
health disparities, lower socioeconomic status, lack of health
care professionals to support reserves and remote areas, impact
of climate change on health, etc. “Medical laboratory assistants
are on the front line taking samples from patients and it is
important that they be equipped to manage themselves with
all cultures, respecting individuality and personal customs,”
noted Brenda Lee Senecal MLT, Diagnostic Services Manitoba.
Colleges and Institutes Canada2 had previously distributed a
series of environmental scans (2005, 2010) that highlighted
the significant reliance of indigenous people on Canada’s
publicly-funded colleges, institutes, polytechnics, cégeps and
universities with a college mandate to obtain education as well
as the barriers for their recruitment and retention, the main
environment in which our medical laboratory professionals are
taught.3
   With the change in government, Christine Nielsen, CSMLS
CEO, and I knew it was the right time to shine light on the lack
of information our organization and profession seems to have
on the topic. One of our first steps was to attend the “Working
With Aboriginal People: Recruiting and Retaining” education
session in April 2017, held by Winston McLean, President
of Iron Wolf Consulting and Lionel Laroche, President of

          employees is to hire the best talent in the industry. But hiring the best of the best isn’t
          all there is to it. It’s about hiring, training and retaining top performing employees and
building a solid team for your lab. This is called talent management.
     “Talent management is about engaging the appropriate workforce,” says Kris Bailey,
Chief Executive Officer at In-Common Laboratories in Toronto, ON. During her session at
LABCON2017, Bailey spoke on the subject of talent management and explained that it is more
than just recruiting the best people for the job. “It’s about challenging and engaging people and
it’s about how you work as a manager or leader in the organization,” she explains. “When you
link all of those pieces together, it’s talent management.”
     During her session, Bailey touched on Maslow’s Hierarchy of Needs, which is a motivational
theory in psychology comprised of a five tier model of human needs1. Maslow stated that                    When you’re looking for staff, you’ll want

Sample carry-over study
The sample carry-over equation presumes that any differential
between each of the three high samples and each of the three low
samples should be attributable only to within-run variability if
there is no carry-over. In this carry-over study, the first trial gave
the value of k to be -0.0001439 and the second trial showed k=0,
which indicates that the sample carry-over is negligible (Table 2).
