After a recent merger at my employer, had some people in of the teams at my office with very little responsibilities for most of a year. The first six months they had minimal work because the company hadn't told them yet they were dropping them for a competing team on the other side of the merger, then they did inform them and gave them 3 months to find a new role in the company and apart from the odd production incident on their system, there was basically no work incoming to their former team.

I think 3-4 moved within the company, 3 left on their own time before the deadline, and 4 waited out for the redundancy payment.
