I know in the US workers are basically serfs, but Twitter is a global company and these changes will run into legal trouble at least in Europe. He’s going to do a moonwalk on a lot of these changes and appears he’s already started.As long as it's clear in the contract, then it's fair game. The employees know what they are going in for, and can make better decision. At least it's not in many other companies who said 40 hours week but then implicitly require you to be 75 hours week. I'd rather see the company being upfront about the working requirement and condition.
