Dental Benefits Overview

Plan Year: 01/01/2016 – 12/31/2016

T-Mobile offers two dental options through Delta Dental of Washington. Both plans provide the same level of benefit and cover the same services. There’s no deductible for preventive care. For other services, you must meet an annual individual deductible of $50, with a maximum of $150 per family.

• PPO Network Dental Plan: This option covers care through the Delta Dental PPO network only. That means you need to select

a dentist in the Delta Dental PPO network and services from a non-PPO dentist are not covered.

• Open Network Dental Plan: This option provides the same reimbursement levels and annual plan maximums as the PPO

Network Dental Plan, but gives you the option to seek dental treatment from the dentist of your choice.

Employee Assistance Program (EAP)

Confidential help is available 24 hours a day, seven days a week to all T-Mobile employees and their families. Available assistance includes counseling for personal or job-related concerns, substance abuse, legal or financial advice, and referrals for child or elder care.

Educational Assistance

T-Mobile employees who have completed 90 days of

employment (one year for part-time employees) may be eligible for financial assistance for classes directly related to their position. Classes must be approved in advance. Reimbursement is based on the successful completion of the course (C or better = 100%); up to $5,250 for full-time employees, $2,500 for part-time employees (as defined in the Employee Handbook) annually.

Adoption and Surrogacy Assistance

Life is full of big steps. First prom. Graduating from school. Getting an awesome job at T-Mobile. Maybe bigger than any of that is becoming a parent. But some people may need help to achieve that goal, such as adopting or using a surrogate to deliver the baby. That’s not cheap — costing anywhere from $20,000 to $80,000 or more.

To help reduce the burden of that expense, T-Mobile offers up to $13,400 per child in Adoption and/or Surrogacy Assistance for eligible employees. Regular full-time and part-time employees are eligible for this benefit on the first day of the month following 30 days of employment and must be employed at the time that adoption/surrogacy expenses are incurred.

Back-Up Advantage Care

We have partnered with Bright Horizons Family Solutions to offer T-Mobile employees the Back-Up Care Advantage Program. It gives employees access to a national network of high-quality care solutions for both children and adult/elderly family members when regular care arrangements cannot be made. This program provides employees a measure of assurance that their family members are being cared for by a knowledgeable and licensed caregiver. Programs available are center-based Back-Up Child Care, in-home care for well and mildly ill children, and in-home care for adult or elder care.

Employee Life Insurance and AD&D

Life insurance provides benefits to your beneficiary in the event of your death. Accidental Death and Dismemberment (AD&D) insurance supplies benefits if you die or become dismembered in an accident. Regular full-time and regular part-time

employees are eligible for both types of coverage.

In recognition of this, we offer employees a chance to take a day away from work, with full pay, to participate in the company’s national employee volunteer program when an event is held in their area.

Paid Time-Off Programs

Taking time away from our jobs to re-charge, to be with loved ones, or to run those essential errands is important to us all. With the T-Mobile PTO program, our employees get more flexibility, convenience, and control over how they want to manage their time off for life’s experiences.

Employees will begin accruing a higher PTO rate in the pay period in which they have completed 3 and 7 years of service. For example, an employee hired 04/01/2015 will begin to accrue at a higher PTO accrual rate on 04/01/2018 and again on 04/01/2022.

In addition, there are nine paid holidays per year. Regular full-time employees will be paid based on their regularly scheduled shift. Regular part-time employees are paid up to six hours for each holiday. Temporary employees are not eligible. Employees may roll over up to 80 hours of PTO from one calendar year to the next.
