Starbucks employees still endure irregular hours, insufficient rest and difficulties taking sick days, according to a new report, more than year after the company promised to improve labor conditions for its employees.

More than 200 baristas across the country responded to the survey that formed the basis of the report, which was released by the Center for Popular Democracy. About 25% of employees said they had been asked to close a store and open it the following morning, giving them little time to rest between shifts. Almost half said they received their schedule one week or less in advance, giving little time to plan for childcare or other needs. Two in five employees said they faced difficulties taking sick days.

Last year, the company promised to change conditions for its employees, which it calls “partners,” after a New York Times report documenting the struggles faced by many employees.
