If you had to lay off your employees in response to the lockdown, and they're now on unemployment, they may not want to come back to work - thanks to the brilliance of our bureaucrats. In some states they may actually be making more money by being on unemployment than by working for you.
While outsourcing can't replace all of your employees, it can hold the fort for some of your people, such as those in sales or marketing, until demand is there, and they're ready to come back.
