Zillow is adopting a hybrid model of work, but its CEO says it's trying to prevent one major downside: a 'two-class system' where those who come into the office are viewed as better employees

What Barton is alluding to is that idea that employees who choose to report to the office either some of the time or full-time could be viewed as more dedicated and more engaged than those who choose remote work. Over time, managers may begin to view the employees they can see working in person as more productive than those who they only see over video chat.
