Surely any contract you're in for a project will have a force majeure provision so you can claim relief?
If it was fulfilling a contract I suspect you'd be right but it's internal projects. We're being told it's "critical to the business" that we carry on working so I guess the implication is that if we don't keep working the business fails regardless of what happens with the virus and the economy. If that is true then I cannot see how the business is going to survive the inevitable recession and lower demand.
