I work in Los Angeles at a retail chain that annually announces record profits each year. The last raise that we had, they made it known that at our location those who worked 2 years or more would be earning $16.83 and the rest of employees would be making $16.50 (and this would also be the starting wage for new hires as well). I hit my 2-year mark with this company back in December 2nd of last year, but I am still making $16.50. Is this an instance of wage theft?
