Coronavirus update: Businesses worry about the "how" of opening back up| Phil Molnar, Brittany Meiling

San Diego is closed for business — but it won't be forever. Recently announced federal guidelines suggest that some doors will open sooner rather than later, leaving local proprietors and landlords in the tricky position of needing to make room for radical change right away.In a press conference Thursday, President Donald Trump revealed a three-phase plan to reopen businesses, starting when each state meets a threshold of coronavirus case decline. Reopening would begin with restaurants, movie theaters and sporting venues. Later on, worksites and schools will reopen — all with appropriate social distancing. Some states, like Texas and Florida, are expected to begin reopening as early as late April, while others will wait longer.That means, across the county, human resource staffers and business owners are already huddling remotely to write a new rule book for returning to work or play. They have large blanks to fill in because there's only one certainty: Leave-your-home life will, for the foreseeable future, be different than what we experienced in the days before COVID-19 upended everyday life.
