I'm not sure that covid lockdown has proved things can be done differently - we're all bankrupt !!
What a silly comment.
It has very much proven that things can and will be done differently, a good example would be my ex-MD, he was dead set against allowing his office staff (more specifically sales) to work from home at all, as he claimed it was inefficient and would hurt productivity, writing it off without even trialling it with a few of the staff.
Having been forced into the situation over the last few months, my friend (or ex-colleague) has been keeping me up to date with the changes that have taken place. Everyone of the office staff has been relocated to home, sales included, they have all been given new laptops if they didn't have one already, they have all be given a broadband allowance or connection, and a secondary mobile back up for fail-over. They have been told as of June that 90% of them will be no longer required to go into the office more than once per month, and that all of the company cars, baring two pool cars are being stopped, and special application must be made to justify keeping the one they have now. They've hired three additional I.T. staff, and have a new help desk arrangement for issues, and the target time for resolution has been dropped from 24 hours to 30 minutes, meaning things stay broken for less time, and more gets done, this has been shown as productivity (and sales) have all gone up and communication has become much better (so I am told, it was terrible), hence the commitment to keeping this as the 'new normal'.
So that is around 40 people no longer commuting every day, wasting time, fuel, and many other things, while allowing more family time, less cars on the road(s), and every single one of them is better off financially as no wages have been cut, and they now have less bills to pay, so technically they've all had a pay increase (baring those company cars). The only loser in this will be the lease holder on the office space when the lease is over, as they will be looking to move into much smaller offices, and maybe even looking at using the daily/weekly office rental companies alongside a storage/industrial unit instead.
Tell me again why things can't be done differently?
