Is it legal for a private company owner to change an employees wages at any given time?
Question Details: The owner in the establishment I work at has paid me commissions for 2 years. Now, out of nowhere, they want to change it to hourly pay.
Yes, it is perfectly legal so long as you don't have a written employment contract which is still in effect (i.e. not terminated or expired) which locks your current compensation in for a set period of time (e.g. a one-year contarct or commission agreement). When there is no contract, the employer determines all aspects of the job (a consequence of "employent at will," which the law of this country), incuding how and how much employees are paid, and may change the job or compensation at will.
