courtier:
(plural: ‘courtiers‘; pronunciation: the letter ‘c’ is said with a ‘k’ sound)

a queen with her courtiers
(in olden times) a noble person who attended at the court of a king, queen or other ruler;
(in present usage) a person who admires/flatters (talks very highly of without any true/real feelings) somebody in power or position in order to get some personal benefit or favour;
a flatterer; a sycophant; a hanger-on,

present-day courtiers, praising their boss for nothing
Each of the courtiers of a King had a specific duty to attend to before and during a court session.
Though it was a privilege to be a courtier attending the court regularly, the life of a courtier at some Kings was very risky because a disappointed king might often show his temper on the closest courtiers.
Our new manager is known for favouring those who praise him, and so, it’s no wonder he has several ‘courtiers’ around him praising him all the time.
