Witnessing tragedy of the commons, literally

There's some open space outside our factory compound, and likewise, every factory in our industrial area has. This space is of course meant for easy movement and manoeuvring of heavy vehicles which frequently visit these factories.

Don't know who started it but now some factories are seen stocking their material (natural stone) outside their compounds. Means, in the space that is common to all.

The other day we found that another guy has installed some shanties for workers in the common space. The guy is insistent that he would continue to use that space until others stop doing the same.

And the movement of heavy vehicles into and out of our compound has become slightly inconvenient for the last few months.
