About Mill Rock Packaging

Mill Rock Packaging is a private equity backed specialty packaging platform that has grown quickly through acquisition. The company started with one site in 2020 and has scaled to seven sites in five years, bringing together formerly independent and family run plants into a single platform of about 700 employees across multiple regions and time zones.

As Talent Director, Megan Taylor leads talent acquisition, learning and development, performance programs, and internal communication and engagement. Her remit is to bring great people into Mill Rock and build the programs that keep them there, while aligning seven legacy cultures behind one evolving story.

“Broadly speaking, my role covers everything from bringing great talent into our organization to programs that help keep that great talent here. More recently that has included employee engagement and communication, with ChangeEngine as our major resource to support those efforts.”

Challenges

Rapid growth, fragmented communication

Mill Rock grew from one site to seven through acquisition. Many locations were formerly small, independent or family owned operations that relied on informal, face to face communication.

“When you are a smaller shop you can walk onto the floor and share a message. Once you are at about 700 employees across different time zones you start to have the challenge of how do we communicate consistent messaging.”

Employees across sites were asking the same things:

  • How is the company performing
  • What is the direction of the organization
  • What is new, who is new
  • How do we get to know our leadership team

“We heard a lot of feedback from employees that we do not know what is going on.”

Mixed channels and missed employees

Some employees had email, some did not. Some worked at desks, others on the production floor. There was no single way to reliably reach everyone.

“You did not have the ability to just send out an email and update everybody or put up a poster and update everybody. A lot of employees were getting missed in communications.”

Manual programs, no data

Important initiatives, like the Continuous Improvement (CI) newsletter, safety campaigns and event invites were:

  • Built manually in Word
  • Attached to emails or printed and left in break rooms
  • Impossible to measure for reach or engagement

“We had no ability to understand what people were engaging with. Were people opening the CI newsletter, were they using it.”

Overloaded onboarding and stretched managers

New hires were flooded with information in their first days and retained “maybe 20 percent” of what they heard in orientation. There was no structured way to reinforce key messages over time.

Production managers often had 30 to 50 employees on their teams and frequent new hires. Expecting them to remember every 30, 60 and 90 day check in and every reminder was not realistic.

Solutions

Segmented, multi channel communication for production and non production teams

With ChangeEngine, Megan’s team now segments by production vs non production, location and role, and uses an omni channel approach:

  • SMS for production and non email employees, which is their preferred way to receive updates
  • Email for non production and desk based staff
  • Posters and QR codes in facilities to support campaigns and events

“We know that our production employees are best accessible via SMS text message. We know that our non production employees generally prefer email. We are able to tailor messages for each of those groups from one platform and keep a consistent tone that is true to who we are as an organization.”

Onboarding journeys that support both new hires and managers

Instead of overwhelming new hires in week one, Mill Rock has mapped an onboarding journey across the first month to month and a half:

  • New hires receive spaced messages on performance reviews, intranet resources, and key processes
  • Messages are scheduled a certain number of days after start date
  • Managers are CCed so they see what their new hires are getting
  • Managers receive their own reminders for 30, 60 and 90 day check ins

“We have been able to be strategic about what information they need at what point in their onboarding journey and automate sending it. We do not have to put reminders on calendars, it is just automatically getting sent.”

This is especially important in plants where a single production manager might have 30 to 50 people and new hires joining every week.

CI newsletters with flipbooks and real analytics

The CI program is central to Mill Rock’s quality and efficiency goals. The CI leader previously created quarterly newsletters in Word and attached them to emails or printed them for break rooms, with no way to see who read them.

With ChangeEngine, Mill Rock now:

  • Publishes the CI newsletter as an electronic flipbook that simulates page turning
  • Sends it by SMS to production employees and email to non production employees
  • Still prints a PDF version for break rooms

Most importantly, they can now see:

  • Who clicked and opened the newsletter
  • How much time people spent in the document
  • Which sections got the most attention

“There was actually a tremendous amount of engagement electronically, which was a wonderful thing. Now when we go to do it again we can tailor the content based on what employees actually engaged with instead of just assuming.”

Safety campaigns that show real care

Mill Rock used ChangeEngine to run a summer safety campaign with weekly messages on:

  • Hydration and heat safety for employees in warm manufacturing environments
  • Family focused topics like swimming safety for kids and beach and pool reminders

“We got quite a few messages back from employees, especially non production staff, saying thank you so much for this message. That kind of feedback shows the genuineness and intention of the message really did come through.”

Automated events and recognition

For the company barbecue, Mill Rock:

  • Created posters with QR codes that linked to a simple signup form
  • Let employees register on their phones with their name and number of guests
  • Automated reminders to sign up
  • Sent event reminders to those who registered

The event team could then download a clean spreadsheet with accurate counts instead of collecting paper sign up sheets.

“We were able to see people go in and sign up after reminders. It was a better experience for planners and for employees, especially those who do not come into an office every day.”

For birthdays and work anniversaries, ChangeEngine:

  • Sends reminders to managers
  • Provides branded templates using Mill Rock’s logo, colors and mascot Boxley
  • Makes it easy to send personalized recognitions that feel special

“Sometimes just the barrier of trying to create the message deters someone from sending it. ChangeEngine takes that barrier out. Managers can send something meaningful very quickly, and employees have said I have never gotten anything like this before.”

Boxley the mascot as a culture carrier

During implementation, the ChangeEngine team suggested a mascot to help unify culture and bring some fun into internal comms. Mill Rock adopted and refined an existing illustration into Boxley, then ran a naming campaign across all sites.

  • Employees could vote via email, SMS and QR codes
  • Roughly 25 to 30 percent of employees participated in the naming
  • Boxley won in a close vote over the runner up name Paxton

ChangeEngine helped write a backstory about Boxley being “created” on the packaging floor, tying him directly to Mill Rock’s work and machines.

“People really had fun with it and we got more engagement than we expected. Boxley serves as a connection point for our culture and helps bring a little bit of fun and energy to our communications.”

Impact

A scalable internal communication system across seven acquired sites

In the first year with ChangeEngine, Mill Rock has turned ad hoc, site specific communication into a coordinated, segmented system that:

  • Reaches production and non production employees in the ways they actually use
  • Gives leadership visibility into who is engaging with what
  • Reduces manual effort by automating recurring communications

“Our leadership team invested in ChangeEngine in a year when we were being very careful about where we spent money. They said, we need this, we hear our employees, we know we need to build trust with them.”

More engaged, informed employees, stronger trust

Employees now receive clear updates on:

  • How the company is doing
  • What is changing
  • Who is joining
  • How leadership is thinking about safety, quality and culture

Through safety campaigns, CI newsletters, onboarding journeys and Boxley themed culture communication, employees see that the company is investing in them, not just sending “check the box” messages.

“If you do not know where a company is going and you do not feel like you can trust the company, you are not going to stay. Through these types of communications we can show who Mill Rock is and where we are going. That relays back to engagement in a very real way.”

Better onboarding, less overload, more retention

By spreading onboarding messages over several weeks, Mill Rock:

  • Reduces information overload in the first days
  • Reinforces key concepts when new hires are ready for them
  • Supports managers to remember check ins and expectations

This improves early experience for both employees and managers and reduces the risk that overwhelmed new hires disengage or leave.

Data driven improvement and stronger compliance

With analytics on CI newsletters, safety campaigns and other messages, Mill Rock can:

  • Double down on content that resonates
  • Adjust or retire content that does not
  • Answer questions like “did this person actually open and engage with this policy communication” when compliance matters

“We get a dashboard that gives us information down to whether an individual employee clicked and opened something. For policies and procedures that is huge.”

Easier events and more meaningful recognition at scale

Automations around events and milestones save hours of planning and coordination while creating a better experience:

  • Company events are easier to plan and communicate
  • Managers can recognize birthdays and work anniversaries in a branded, heartfelt way
  • Employees in all locations feel seen, not just those near corporate

“It is not just about getting a message out. It is about building trust with the organization, which connects directly to how important the company is to the employee and how invested they are in their work.”

Clear link to business outcomes

For Megan and Mill Rock’s leaders, the connection from communication to business outcomes is now clear:

“Ultimately if we have invested, engaged employees, the statistics will show you they are working harder, working smarter and working better. That relays back to productivity and profitability. When you feel like the company cares about you, you care more about the company and the work you are producing for the company.”

Mill Rock’s story shows how a growing, acquisition driven company can use automation and AI not to replace the human touch, but to scale it across seven sites and 700 people, strengthening culture, performance and long term value.
