QMy company moved and downgraded its workspaces from offices to small cubes for everyone in my grade level. I'm not thrilled, especially with the loss of privacy; what can I do to make the best of it?
ARepeat "it's not personal" as often as necessary, and look for alternatives when privacy is a must.
The inner game
Acceptance is key; in a situation like this there is no value in resistance, yet frustration with an apparent decline in work quality of life is hard to avoid. Focus on letting go of any anger or resentment so that even worse outcomes are not created. Use deep, conscious breaths to help you remain calm.
Now take an objective look at the shift to your new environment. Consider the reasons that may underlie this change. It may be related to space constraints. Also, many companies are shifting to a more open floor plan to build collaboration. It'll help to understand your company's objectives. And because everyone at your level is affected, remember that it's not personal, and is not a reflection of your performance.
Think realistically about how you'll be affected. You'll have less privacy, as you've noted, and less space. Are there other external effects? Play a little game with yourself, thinking about the worst things that could happen. Be sure to use words like "always" and "never" to increase the drama. This will help you get a bit more grounded in the likely impact of this change. Also consider positive effects. Will it bring you closer to colleagues and team members? Encourage you to clean house as you move to a smaller space?
The outer game
Start with the most practical aspects of adjusting. Locate spaces that you can use for private conversations with team members, either in person or by phone. Conference rooms, lobbies or work areas, or even the cafeteria are all options. In good weather, getting outside for an informal meeting can open up possibilities.
