In just a few weeks, Salesforce will allow employees in select U.S. locations to return to work in the office, according to a statement the company posted on its website.

Starting in May, Salesforce’s vaccinated U.S. employees in California, specifically in San Francisco, Palo Alto and Irvine, can voluntarily join groups of 100 or fewer people to work on designated floors in certain offices, while following safety protocols and adhering to health mandates, said the statement. The company will have mandatory on-site coronavirus testing twice weekly, as well as health officers to assist employees and ensure they’re following coronavirus safety measures.

The company’s statement noted the move is the first part of its phased reopening plan, which aims to gradually open offices to both vaccinated and unvaccinated employees — at 20 per cent to 75 per cent capacity — depending on the coronavirus data rating and local guidance. Salesforce’s statement said it’ll continue to follow safety protocols and provide testing where possible during this stage, after which it will move to the final stage where its offices fully reopen at 100 per cent capacity, with vaccinations encouraged and testing available where possible.

Salesforce is the latest company to announce it’s beginning the first phase of return-to-work planning. As part of its phased re-opening hybrid-workplace plan, Microsoft Corp. started allowing more employees to work from its headquarters in Redmond, Wash., and nearby campuses as of March 29, said Kurt DelBene, the company’s executive vice-president, in a blog post on the company’s website.
