There's tons of people doing call centre work, so you can certainly track call volume. Then if you're at the clerical level your job is to handle the daily volume of 'stuff' that is your workload. It might be customer invoicing, bill paying, procurement, HR, or whatever, but whether you're in a cubicle or at home, it's your workload and you need to get through it.
If you're a program officer/manager, then again, you have a certain program area you're responsible for. You need to take care of all the issues that pop up from day to day, and take part in a growing number of online meetings (the higher you get, the more meetings). I have a friend who's a senior director and he's in online meetings most of the day every day. Even when he has to go to work he sets up in his office and then does the same online meetings he does at home.
Now let's talk about the office. In June he's losing his. The whole branch are moving to another building that has been 'processed', which means moved over to the new government open office system. Even as senior director he will not have a private office, or even a cubicle. It's all open air stuff and you don't get your own desk. You have to reserve a desk ahead of time on a web application. I know another person who is at the program manager level who has to do this, and then people shush her because she's always in online meetings talking. And so are other people.
Tell me the sense in having people going to work to take part in online meetings. Especially with no offices and no overnight storage. They have to carry everything in with them including their laptops. There's none at the desks. They carry it all in and set up in the morning, then break it all down and take it home in the afternoon. So they can talk online just like they do at home.
Especially since their team might not even be in the same building. Or if they are on the same floor. Or if on the same floor not in the same area of the floor. In the meantime, people who need to concentrate can't. And confidential information that shouldn't be talked about in front of others is being talked about in front of others because there's no other way to get through the meetings and workloads.
