It's had a positive effect for me.
My usual Monday before coronavirus: sofa until 11:00, drive 40 minutes, walk a long way from the carpark and up two flights of stairs, teach 90 minutes, eat, teach 90 minutes, lock office door and lie down for 15 minutes, teach 90 minutes, walk to car, drive 40 minutes, collapse on sofa til Tuesday lunchtime, be lucky to get away with it without a headache.
Now it's: put down my coffee at 12:13, walk downstairs to computer, start lesson at 12:15. I can go upstairs to my sofa between lessons, and after the last lesson no walking, driving or collapsing - back on my sofa 2 minutes after the last lesson. Plus I can sit in my comfortable office chair for the whole 90 minutes whilst I'm teaching, instead of having to stand up and go to the board, hand out documents etc etc. My biggest movement is clicking my mouse.
Plus the uni has just given all part-time teachers a 20% payrise in recognition of the increased workload involved in adapting to teaching online, which is nice.
Same with a lot of my private students - I save a 40 minute drive per student, and a lot of petrol money.
Downside is that some private students don't want to use Zoom, and the ones remaining may soon have to save money and English lessons is the first thing companies cut when they need to save money, but I've lived with the uncertainty of being self-employed for 25 years so that doesn't bother me.
So everyone having to get used to working online has made my job a lot easier. Other than that, life continues exactly as it did before. For me.
