PurposeThe purpose of this paper is to explore the experience of a cohort of staff who transferred from a medium-sized Irish pharmaceutical company to a US multinational, while remaining in the same building as their original employers and colleagues. It highlights the role of acknowledging loss when facilitating employee transition and the co-development of a communication and integration strategy in transitioning to a new organisation.Design/methodology/approachAn exploratory qualitative case study captures the experiences of the senior manager responsible for the business unit transition and a cohort of 32 employees who moved to the US multinational. Conversations between the senior manager (author three) and his academic peers (authors one and two) trace the experience of this team as they transitioned to the new organisation.FindingsInsights are offered through the transition journey – from the unofficial partial-acquisition offer through to the due diligence period and onto the subsequent implementation of the communication and integration strategy. Findings exhibit a co-developed a communication and integration strategy, revealing a largely successful initial integration of the team into the new organisation.Originality/valueThe paper offers a first-hand account of the steps taken in a successful employee transition to a new organisation following a partial acquisition. It describes how acknowledging loss is a valuable first step in the transition process, enabled by the design and adoption of a co-created communication and integration strategy.
