New Employee Welcome Manual

Welcome

Welcome to NorthWestern Energy! We’re happy to have you on our team.

NorthWestern Energy is made up of people from diverse backgrounds, experiences and skills. We share strong values and a vision for a successful future. As a team we work together to achieve those goals. NorthWestern Energy employees are dedicated to providing the safest, most reliable and highest quality service possible to all of our customers.

I joined NorthWestern in 2003 as CFO, and have stayed here because of the great people in this company and because I believe in our mission.

At NorthWestern Energy, we welcome diversity and are committed to treating one another with respect. We challenge ourselves to achieve our goals efficiently and productively, in order to maximize the value we provide to all our stakeholders: employees, customers, and shareholders. We are honored to provide essential services, and never quit looking for better ways to do our work. You were invited to join us because we believe you are committed to these same principles.

Soon, you will receive an email invitation to a brief company overview called “Plugged In” hosted by Human Resources. There will also be an invitation to attend a day-long in-person “Powered Up” orientation that will occur within six months of your joining us. I look forward to meeting you then, if not before!

I hope you make a smooth transition into your new career with NorthWestern Energy. Together, we can do great things.

Avaya Telephone System

Getting Started

• NorthWestern Business desk phones are an Avaya IP Office phone. This guide is intended to get you started using your phone and to help you set up your voicemail.

• Refer to the following pages to see pictures explaining where to find all the buttons.

• Headsets may be used, but those must be purchased separately. The supported model is Plantronics CS540 or newer.

Default Phone Setup

Voicemail

• If you select the line button of your second line while on an active call on line one, the party on line one will automatically be placed on hold.

• While on hold the caller will hear a short beep every thirty seconds.
