No!  This should be obvious to anyone with even a little familiarity with the wage and hour laws (FLSA).  My niece mentioned over dinner recently that she had just been hired at a local restaurant.  She worked all weekend to get “trained,” but does not start earning wages until her first post-training shift.  Small business owners, please take note and don’t make this mistake.  The employer’s practice here is illegal, plain and simple.
