A project manager of the contractor told me, a subcontractor's developer, during a skype call that they totally lost confidence that we will be able to fix the software issues we have. He told me that while the client was in the call, too. And then he demanded to fix the issues ASAP.

Does he really thought that this could speed up the development or that it motivates us to waste our free time for that project? Even more if you know that his assumptions are crap?
