I often didn't take a lunch break in the office and now run errands or do housework.
But I also stop working later now, as I live closer to my childcare than I did at the office. At the office I had to watch the clock for train times and had to leave 20minutes earlier than I really did because the later train got me home too late to pick the kids up.
Now I get to take the kids to after school activities once a week, which I couldn't do before. And I make up the time once they're in bed- because I'm then not clock watching I end up working more hours than I actually needed to make up.
I do wear PJs some days, but that means I get started immediately after the kids leave for school, rather than getting dressed and made up first. I'm always dressed and made up when having meetings with c suit.
I no longer spend time at colleagues desks chatting with a brew and looking at pictures of their holidays or kids wedding- they put may be one or 2 on the social slack channel.
Because I now work permanently from home, head office no longer expects us to travel to them for meetings and holds them all virtually, freeing up several hours of travel time (that was paid and I didn't need to make up).
I've benefitted massively from WFH - my home/ work balance is so much better, my mental health is better, my physical health is better and I'm far less exhausted from the constant overstimulation of the office and commute.
But work has also massively benefitted - I work more hours per week on average. I'm more productive in the hours I do do because I'm less exhausted and not thinking about other stuff. I've no travel time between sites, no checking if a meeting room is free, no moving between meeting rooms, meeting happen back to back and get started on time and immediately.
Yeah I'm sure some people take the piss, but they're the same people who took the piss in the office, always in last minute, first to.leave, longer lunch breaks and constant chats round the kettle.
