A dispute ensued between a trade union and a breakaway union faction, in which each accused the other of breaking union laws and potentially destroying data. Under adversarial and challenging circumstances, Celerity collected over 1 TB of data from 147 individuals at 26 union locations across the United States and Canada. Celerity interviewed all custodians and gathered local and server-based email, as well as non-email files, hard copy documents, and targeted network server files. Celerity also collected email from 59 web-based email accounts. Celerity filtered the data and provided culled results to a client-chosen vendor for further processing.
