slave-driver
Merciless demanding boss
A slave-driver was historically an overseer who forced enslaved people to work, often using physical punishment.
The term now applies figuratively to any boss or authority figure who demands excessive work: My manager is a real slave-driver—she expects us to stay until midnight.
The hyphen is optional.
