Research as much as possible.
Many times, the sole source of fear is a lack of understanding, and a lack of understanding stems from a lack of information. Take some time to research the company you will merge with. What does it do? How does that compare with what your company does? Learn about the markets each is involved in, and stay sharp on related business news. This could help you understand what is really going on in your business and help you see what lies ahead.

Do a self evaluation.
Think long and hard about your current role in your company. What is it that you really do? Make a list of these things and why they are important. While you may not encounter a direct evaluation from someone in your company or in the merger company, these evaluations will happen eventually and it will be better if you are prepared with solid answers and a substantial, relevant task list. Think about what you offer that no one else does, and make a list of accomplishments so you can easily answer to how you contribute to the team.

Make some new friends.
One difficult aspect of mergers is the influx of new people. They might not understand “how things are done” at your business, and you might not understand how things are done in theirs. In some ways, this feels just like being a new kid at a new school and there might be a lot to learn. When training sessions for new systems are offered, go in with a good attitude and be engaged. Not everyone will be able to approach change this way, and it will set you apart as a great worker.

Above all, stay calm! Don’t let fear get the best of you. Educate yourself and maintain a good attitude, and everything will turn out fine.
