Overtime pay which is calculated at less than an employee's normal hourly rate (usually one-half), rather than one-and-a-half times it, as is usually paid in traditional overtime arrangements. It is a potentially derogatory term, so discretion is advised. Overall, I love having the flexibility to work the hours that I see fit; the only downside is that I only get Chinese overtime when I have to put in more time for a project than usual.
