Juanita is the new HR manager at a nonprofit organization that provides food assistance. In initial meetings, her boss Rich outlined many HR responsibilities but conveyed limited authority for Juanita. She wants to contribute more. Juanita learns the organization struggles with qualified staffing due to limited resources. Cash donations are down, impacting hiring. For a class project, Juanita realizes she can study the organization's compliance with equal employment opportunity laws to help improve HR practices and understand her role better.

Part I – Juanita’s World
Juanita is meeting with her new boss, Rich Ryblessi, the
Director of Regional Services. Rich highlights his concerns in

21. the following areas: analysis and design of work, recruitment
and selection, training and development, performance
management, compensation and benefits, employee relations,
personnel policies, compliance with laws, and strategies for
supporting the mission.
At the end of the meeting Juanita returns to her office and
reflects on the meeting. As best as she can determine, HR has
typically been relegated to simply processing paperwork and
counseling people who had questions about issues like health
insurance and paychecks. And although Rich has identified
many important areas for HR, Juanita senses that he really
expects no more from her than he did of the previous HR
Manager. However, Juanita believes she can and should
contribute more to the mission and vision and can help Rich
overcome a number of challenges.
Consider these reflective questions as you will discuss them
further in your assignments:
1. What skills might Juanita have to develop to better fulfill her
role?
2. How might Juanita engage line managers to become more
involved in what has traditionally been HR’s function in this
organization?
3. Which aspects of human resource management would she
want to entrust to specialists?
Part II: Juanita’s World
Yesterday was a bit of a surprise for Juanita as she sensed a gap
between what her boss said he wanted and what he conveyed as
expectations and limits on her authority. It is now Day 2 and
she is excited and ready to go with her early afternoon
appointment with fundraising’s Director of Development.
As she is reviewing past reports on fundraising efforts and
success a visitor stops in to see her. When Melissa, introduces
herself Juanita finds that she is the previous HR Manager who
left the organization about 3 months earlier. Juanita perceives
this is an ideal time to glean what she can about challenges and

22. opportunities. While speaking with Melissa, Juanita finds out
who the real workers are and who just seems to be filling a spot.
She learns that since resources are limited they have struggled
to find qualified and committed personnel to fill numerous
important positions. Juanita finds that the people do care…a
lot…about the mission but hardly think beyond their current
circumstances and most are discouraged with their perceived
lack of impact on their community. When Juanita questions
Melissa about why she left she finds that Melissa had aspired to
have greater responsibility and make a bigger impact but felt
limited in her role in this organization. In a way, this confirmed
for Juanita that she would definitely have to speak with Rich
sooner than later to be sure she understood her authority to do
all she thought she was hired to do.
As she visits with Jackie, the Director of Development, she
learns that the economy has had a negative impact on their
historical donor base. Cash gifts are down and have been
trending down for about 2 years. Gifts in kind, like food, are up
but since it is perishable they must distribute it quickly or it
must be thrown away. And, since gifts are down they have had
to rely more heavily on volunteers. This means their drivers and
those who distribute food are less consistent and reliable. This
is beginning to impact their gifts from donors since they are
finding out that much of what they are giving is being thrown
away.
As Juanita sits in her office at the end of the day she feels she is
beginning to understand the complexity of the issues. It seems
she has limited authority over areas that most HR Managers
have and that the lack of cash is negatively impacting their
ability to hire and retain the right people. Since she cannot
control the availability of cash she will have to come up with
some innovative ways to better hire and retain the right people.
Part III: Juanita’s World
While attending one of her last classes last night Juanita learned
of an assignment she has related to Equal Employment

23. Opportunity (EEO). As she is driving home from class she
realizes that her new employer would be a great source for the
assignment and help her better understand how to do her job
better.
When she met with Rich he never mentioned laws and
regulations that may impact the organizations. And, when she
thinks about it, she had assumed that since they were a non-
profit doing work to alleviate hunger that they would somehow
be exempt from government oversight.
Her appointment for Day 3 has cancelled so she decides to use
the day to learn what she can about laws and regulations that
they could be potentially violating and also try to better
understand how they could use them to their advantage.
After about 2 hours of research she has learned:
· Full time employees number between 15-30 people depending
on the year and workload.
· They receive both federal and state contracts. Each is for
$20,000 per year.
· Periodically they hire people who serve in the National Guard
and Reserves.
