It documents how scheduling software in the retail and food sectors has allowed corporate chains to optimize the scheduling of low-wage workers, scheduling them for shorter shifts concentrated at peaks hours and sending them off when not needed.
This article doesn't go into great detail about another exploitative practice: the split shift. This means a employee may be required to work a short morning shift and a short evening shift, making it effectively impossible for those prepared to scrape by working a second job to even do that any more.
The net effect is less wages and less benefits for workers. And to whom does the difference accrue?
Technology here acts as a tool further disadvantaging those who are already at a disadvantage. And technology itself doesn't offer an obvious remedy. Collective action among workers might help their cause, but unions in this country struggle to organize. Facebook and Snapchat don't appear to be picking up the slack.
Government regulation would seem to offer a more civil remedy. Simply don't allow employers to squeeze their employees like this. But while I continue to hear occasional media stories and personal narratives about these abuses, I haven't heard reports of any serious proposals to end them.
