A promotion without a raise. The act of changing an employee's title without due compensation. The addition of job responsibilities because the employee "deserves a challenge."
To thank you for your good and hard work, we'd like to offer you a title change to 'King of France'. This fauxmotion will not include a raise but you do get new business cards.
Fauxmotion: -noun foh-moh-shun artificial, imitation or fake advancement in rank or position. A fauxmotion can only be identified by the fauxmoted and the fauxmoter due to the illusion of a promotion by external parties, as increased workload and responsibilities are required. A fauxmotion cannot be officially legitimized by title and/or compensation.
Jane: Congratulations on your new promotion, Athena! You really deserved it.
Athena: Thank you, Jane. Unfortunately, I received a fauxmotion, as I will not be receiving an increase in pay or a higher title. It sure has increased my workload, though!
