I disagree in that it sounds like the OP's organization is staffing to the limitations of their technology. It reminds me of working in subversion where people would never collaborate for fear of commit collisions. This super bad from a knowledge perspective in that people don't cross train and instead become reclusive experts that they use to justify their existence and continued value. For me, personally, the biggest win of git is ease of branching allowing for rapid and easily disposable experimentation in the source code.
