I'd like to see how he'll handle this "inconvenience". Since he's asking companies to pay this kind of wage, maybe he can provide an example by doing it himself.
Now that the Sanders campaign is in full swing and people are working tons and tons of hours they may be earning less than the $15 minimum that they wanted. This is sometimes the case in other jobs when you take on a salary position, as you're paid for your year and not per hour.
Do you think they'd ask for more than $15 if they think they are actually working more hours than they expected?
I highly doubt he's ever going to pay his own workers -- the low level ones, $15 an hour. It'd be too expensive to run his campaign like this -- unless he wants to use this as a marketing stunt and pay everyone $20 an hour or something along those lines. Could be good advertising.
Well yes, they would without a doubt have asked for more if that was the case. But it's not.
