A: In the event that your boss is unavailable due to sick leave, to whom do you report?

Note: This term from Latin means “for the time being.” “Pro” means “for,” and “tempore” is the ablative singular of tempus (“time”). This signifies “limited in time, but less fleeting than what is temporary.” The short form “pro tem” is also commonly used.
