Due to circumstances associated with COVID-19, there was an exception made last year to allow employees to carry over additional leave into 2021. The University System of Maryland has published the terms of the exception in two documents: Faculty Temporary Exception to Annual Leave Carryover and Staff Temporary Exception to Annual Leave Carryover.
The documents are available on the Human Resources website, under News and Noteworthy at https://www.umaryland.edu/hrs/.
