The degree distribution of a network generated with 10,000 nodes shows two peaks representing the combination of workplace interactions. The first peak at k ~ 6 is due to the scale-free network of non-essential workplace interactions and the second peak at k ~ 25 is coming from the random network of essential workplace interaction. The high-degree tail represents the hubs, i.e., the individuals who have many interactions, who could therefore act as super-spreaders if infected
