Schleisinger stated in the memo that Thomson Reuters has done its best to cancel open posts that don't fit within the new organisation, and also to move people into new roles instead of cutting their jobs when possible.

“When two similar and once competing organisations come together, there is natural overlap and duplication in coverage,” Schlesinger wrote, according to Reuters UK.

The UK National Union of Journalists said it will negotiate with Thomson Reuters, but if the two fail to see eye to eye, the union has not ruled out a strike, Reuters UK reported.

Thomson Corp. bought Reuters Group Plc for more than US$16 billion in cash and stock on April 17.
