I've already pushed back against my employer wanting to deploy this sort of monitoring in the workplace. There are significant gaps in work flows and duties which cannot be captured by it for starters, which makes the metrics useless to use across the entire organisation, it's an indicate of some work done but nothing else.
I raised at the start of the year that working from home requires 4 things:
1. Internal infrastructure or resourcing to enable it.
2. Suitable equipment and workplace at home with an employee who wishes to work remotely.
3. An employee who can be effectively managed remotely - not everyone can.
4. Managers who are trained in how to remotely manage staff - this is a new skill for all of our management.
So far 1 and 2 have been addressed, 3 and 4 remain untouched. Fact is some people should NOT be permitted to work from home and some managers should be removed from their role or given training as they are unable to properly manage staff remotely.
These are not IT issues, this is meatbag issues (staff/manager), require training and potentially going back to office worth with appropriate social distancing measures in place. Which should be possible given so many can work remotely. I have not worked remotely at all, I have always been in the office despite enabling 12000 staff to work remotely.
