In a previous job, I was trying to organize a common repository with our shitty business partner so we could both be able to contribute our part so our work would not overlap. Not like they cared anyways.

One thing I quickly noticed is those fuckers would just straight up commit untested changes on master and cripples our whole testing and prod deployment at times because we were depending on a shitty IoT service they provided us onto which we had no control whatsoever.

I told my boss, who was often complaining about them being unreliable in the first place, I would simply restrict them from merging and commiting to develop or to master without my approval. We cannot keep working like this.

He told me that we could not impose on them our work practices and that I should not try to piss them off. To be diplomatic.

I politely and professionally refused to do it, but he did change his mind in the end. He and I left not too long after. I guess he felt obliged to respond that having his job at stake but you cannot condone voluntarily shitty work.
