TRIQUINT EMPLOYEE FREQUENTLY ASKED QUESTIONS

Will the sabbatical policy change after closing of the merger? For example: employee is due to receive his 25-year sabbatical in November 2014, and is concerned that he will not receive it if the policy changes after closing of the merger.	We are currently comparing all of the benefits and policies of both companies. Although we have not made any decisions with respect to sabbatical policy after closing of the merger, we can assure you that sabbaticals earned before the closing of the merger will continue to be honored.
Will we continue to pay overtime in manufacturing for compressed work-week hours over 8 hours in a day?	Both companies have a variety of work schedules and pay practices. As part of the integration process, we will review pay practices across both companies and across all of the different factories. We will provide an update on our review and related decisions at a future date.
With this merger pending, I am concerned about our medical insurance, PTO/holiday, & sabbatical. How is the merger going to impact our insurance & time off? When are we going to know if any changes are going to be made?	As part of the integration process, we are comparing all of the benefits and policies of both companies. While your benefits may look different after closing of the merger, our goal is to maintain market competitive benefits and policies in the aggregate.
