Thing is, IBM does not have a great reputation for how it manages its staff as it tends to favour moving positions to low cost locations and redundancies that provide the minimum possible payouts

e.g.

(and that's just from this year)

they also have a reputation for being primarily concerned with the bottom line (profit-wise) over other drivers.

So concerns around how they'll manage this kind of acquisition seem at least somewhat justified.
