Under the Displaced Janitor Opportunity Act (Lab. Code 1060 et seq.) a successor janitorial company must hire the janitorial workers of a predecessor company at the same site for at least 60 days after taking over the site.  Here, the building owner supposedly terminated the janitorial service contract on the 13th of the month and claimed that there were no janitorial employees on that date–which was true only because the owner fired all the janitorial employees three days earlier.  That ploy doesn’t work.  The actual date of termination was when all the janitorial workers were let go.
