Coaching the project team on compassion, empathy, patience, and mindful leadership would be beneficial. Project managers, leadership, and project leads of the acquiring company tend to be laser focused on the integration tasks and hitting targets and deadlines and disregard the human needs of the team. This may sound new age-y, but I’m a strong proponent of having a gratitude practice and showing recognition. This could be done at the start of a weekly meeting and through thank you notes to team members, especially the incoming team from the acquisition. At the start of a meeting, the meeting lead should take some time to call out what they are grateful for/articulate appreciation regarding the team and their work, and then open the floor to anyone else who wants to share. From a scientific perspective, the integration is shaking up the acquired team’s basic needs of belonging and stability. Some of this can be offset by showing appreciation and making them feel belonged to the new team.
