I'm a social worker and although it has been horrific there have been some positives:
We used to have lots of meetings and still do, but now those meetings can be organised quickly and involve many more relevant people because people aren't having to travel to one place for them, they can sit at their desk, attend virtually and dip in for the bits that they are needed.
Rather than being able to have 2 waste of time meetings a day I can have 4 that are mostly useful.
The savings on staff mileage reimbursements costs to the local authority must be HUGE. Hopefully they can spend that money on services for vulnerable people and potholes instead
We have also been able to 'see' otherwise hard to reach people more easily, people have been happy to have a discussion via WhatsApp or teams, for parents they haven't had to take half a day off work to meet with us (e.g. we can do a WhatsApp call while they sit in their car during a lunch break) similarly people who might have declined a visit because of embarrassment about their living conditions have been happy to talk to us using virtual means.
We've had really low sickness rates because people aren't forcing themselves into an office to catch all the bugs, or if they have been feeling under the weather they've still been able to catch up with paperwork at home.
And my favourite of all, I can actually bloody park when I do go to the office.
