HaveMyShift helps hourly workers and managers. Swap shifts with co-workers and get reliable coverage in under-staffed workplaces!

HaveMyShift is an online marketplace for the 74M hourly workers in America. We allow them to trade shifts with one another, giving them options to choose a better work schedule for themselves. We have helped over 5500 employees in companies like Starbucks trade over 42,000 hours of shifts to-date. For every shift traded, one employee gets more personal time, the other employee gets more work, and the company has a workforce that is happy to be there.
