The main thing I hated about working from, apart from not having the space to have a proper desk setup, was just feeling constant anxiety about not feeling productive or maybe more so not being seen to be working. And I don't really know why I experienced this, because we don't have that sort of culture at all. However this lead to poor sleep and stress.
I know a lot of people much prefer working from home, and most of if not all of my coworkers do, but I do feel like a lot of the conversations around WFH, especially from software engineers, is WFH is brilliant with no downsides, and the conversation completely negates the people that dislike it for whatever reason
