The WARN notices have been sent to ABM employees, about 800 will be laid off. United won the recontracting talks and will get about 2/3 of all work - ABM will keep some work - many people who work for ABM today will be hired by United, but let's see how that pans out and how many folks will actually completely lose jobs.
I do not think they have any stats on this - anyhow, ABM will be hit big time.
