Flight Attendants who place themselves on sick leave
during the period starting July 1, 2019 – July 7, 2019 will be required under the terms of our JCBA to supply United Medical with an Absence Certificate (Section 13.C.4.). 

Flight Attendants using approved FMLA during these specified holiday dates are also required to provide the Absence Certificate for any sick leave used during this same period. There is an exception for those Flight Attendants who have had no absences during the prior twelve (12) calendar months who are not subject to the Absence Certificate requirement that applies during the designated holiday period.

Detailed information is available at unitedafa.org or by referencing Section 13.C.4 of our JCBA. See your Local Council Representatives for any additional clarification.
