At the end of 2017 (or put another way; at the start of 2018) IBM had a global workforce of ~366,000
Red Hat added (in 2019) ~13,000
At the end of 2020, (start of 2021), IBM had a global workforce of ~346,000
So, 366,000 + 13,000 = 379,000 (potential total employees) – 33,000 (reduction in workforce totals) = 346,000 (Start of 2021)
Now, IBM does lose employees to natural attrition, which usually are replaced 1/1 possibly in different areas, in order to maintain a viable business. But given IBM’s history, clearly much of the reduction is through unnatural workforce actions.
Lets keep going…..
For 2018-2020 (three years/all), the amount allocated for “workforce rebalancing” was;
~$600m (2018) +~$555m (2019) +~$2b (2020) for a total of ~$3.155b.
So given that IBM reduced it’s workforce by ~33000 for 2018-2020 with $3.155b allocated, and that IBM has allocated $3b just for 2021, we can guestimate that IBM will reduce its workforce by another 30,000 or so over the next 12 months. Then there's the the other $1b for 2022. But of course that may change. Once SpinCo is out the door, that leaves ~220k. As others have said here previously.
Depressing isn’t it
