Oh, you WFH? We can offshore it then
One of the perils of working from home is eventually a bean counter gets it in their head to offshore the work entirely. "Why should we pay someone here who is working remotely when we can pay someone much less overseas to work remotely?" The company I work for has been doing just that - anyone who was working from home was more likely to have their job offshored. They are moving jobs overseas anyway but it was more likely if you aren't seen in the office regularly (even though more often than not my manager rarely came to our site.)
Some of my colleagues work from home 2-3 days a week. I work from home only on the weeks that I am oncall (2 hour commute each way) - statistically I'd get a lot of calls during the drive to or from work so it makes sense to WFH when oncall.
With the cuts to staff came a cut to the office space we have (our new exciting 'Agile workspace' - if all the different teams had all their people come in on the same day there literally would no longer be enough desks for us all.
