Starbucks is requiring some remote workers to return to its headquarters and increasing the number of days that corporate employees are required to work in an office.

In a letter to employees posted on Monday, Starbucks Chairman and CEO Brian Niccol said corporate employees would need to be in the office four days a week starting in early October instead of three days a week.

The Seattle-based company said that all corporate “people leaders” must be based in either Seattle or Toronto within 12 months. That is a change from February, when it required vice presidents to relocate to Seattle or Toronto.

Starbucks said individual employees working under those leaders would not be asked to relocate. But the company said all hiring for future roles and lateral moves will require employees to be based in Seattle or Toronto.

Mexican tomatoes hit with 17% tariff

The U.S. government said Monday it is placing a 17% duty on most fresh Mexican tomatoes after negotiations ended without an agreement to avert the tariff.

Proponents said the import tax will help rebuild the shrinking U.S. tomato industry and ensure that produce eaten in the U.S. is also grown there. Mexico currently supplies around 70% of the U.S. tomato market, up from 30% two decades ago, according to the Florida Tomato Exchange.

But opponents, including U.S. companies that grow tomatoes in Mexico, said the tariff will make fresh tomatoes more expensive for U.S. buyers.

Tim Richards, a professor at the Morrison School of Agribusiness at Arizona State University, said U.S. retail prices for tomatoes will likely rise around 8.5% with a 17% duty.
