I think the issue really lies with the VPN that companies provide. In normal times they have enough capacity as a lot of people are in the office but with everyone working from home there isn't sufficient bandwidth to go round everyone. Earlier in the year my employer had to ask people north of Coventry to use the secondary VPN, which was only ever designed to be a failover option in times of outage, whereas before everyone would be on the primary connection without any problems. Some companies will have upgraded their VPN capacity but I expect some will have a make do attitude and not increase VPN capacity.
My employer had a VPN which was used by a minimal amount of people before Covid came on the scene. It was gradually rolled out to more people (including myself) to see how it coped, and I believe there has been some upgrade work too. It works fine for me 99% of the time. One of our senior management said something along the lines of the situation has brought forward what would probably have occurred in a few years time.
We all still pay tax and use our local shops....
I've found myself spending more money on my local high street, and slightly further afield. I pop down to the local butcher's shop for a pork pie or similar for lunch at least once a week, and also try and have 'lunch out' one day each week, which can entail something like a 2 mile train journey, visit the privately run station cafe for a sandwich and drink, then walk home. Not only does it get me out, it supports local businesses and a good form of exercise, although my walking route now has to be via the main road, as the more pleasant walk over the fields has become too boggy! I suspect my spends are broadly in line with what I would spend in the shop/staff restaurant at work.
Conversely I know of employers who have paid their staff to buy desks, monitors etc for home use - the increase in productivity will more than pay for this initial cost. Always worth asking
I've been told I can bring my chair and a monitor home from work. But I already have a computer chair, and a second monitor wouldn't fit sensibly on my small computer desk. I'm managing to do my job on a laptop, and although certain aspects of it are better done with two screens, I'm surprised at how quickly I adapted.
Looking ahead, I can see me doing a mix of home and office working, which - for my circumstances - is a 'best of both worlds'. There are some parts of my job which are certainly better done in the office, but there are others which can be done just as well from home. There are other advantages of being able to work from home on occasions - for example, this morning when I woke up to 2 inches of snow. While I would have battled in to work (and probably arrived late), others would have rung up and said they couldn't get in. If you can work from home, then the disruption for both the employer and employee is much less. On another occasion, a recurring health issue I have flared up the other week - I was able to work from home, but wouldn't have been able to go in to work, so no sick day needed.
