Answer:Quid pro quo case
Explanation:
Qui pro quo is a Latin word which simply means "something for something", that is an exchange of wants of great values.
Anita asked for sexual favour from her employee, Bert, in exchange for him to retain his position as the manager but his refusal caused him to lose his position as the manager to a common secretary.
Quid pro quo indicates that an something has been traded in return for something of value. Quid pro quo exist in a business organization when the business owner propose to promote an employee if he/she could fulfill their desires. In the case of Anita and Bert, the desire could be seen as 'sexual desires' in other words, sexual harassment by Anita to her employee.
