I not sure what is worst, an arrogant client full of demands or anti professional collegues who don't respect you and try to subvert your work

We are a small team. 2 developers and our leader. We spend our day trying to fix the issues and for troubleshooting and our leader, who just send excel sheets, talk with the client, assign his tasks to us and watch series at Netflix complaints if we work only 10 hours per day....WTF?

We have to deliver a new functionality in 2 weeks and the client hasn't share with as the specs of the flow and the business details yet.
So until today we had developed the half functionality believing that our system will communicate with Web services with a third - not the actual one.
We figured it almost by luck, when randomly, a colleague from the third system made a funny comment.....
