I just sent this to the U.S. Department of Labor:

Grubhub has a set up that makes you accept 95% of their offers to reach their 'premier' status. The premier status lets you schedule delivery blocks on an earlier day than other status levels do. They recently started a very unfair practice of allowing premier status people to set their availability and then they will schedule the blocks before the day it is allowed in the app. They play favorites and purposefully harass people that they want to quit by not giving them any blocks through the advance scheduling or scheduling them outside of the availability that they set. If you wait until the very minute that the premier status is supposed to let you start scheduling blocks they are all gone except for the ones that no one wants. This is not a fair business practice as they have no checks to prove that they do not discriminate against certain contractors. Also, The whole gig industry advertises as work when you want and where you want, but then the penalize you if you do not work when they want you to and where they want you to. Sounds like fraud to me. FYI, The entire industry is set up to benefit restaurants, especially large chains, and the app writers. It is specifically aimed at taking advantage of minorities, immigrants and marginalized groups.
