to make sharp staffing cuts. east bay professor , nolan higdon, teaches history and communications. he says he is not surprised by the effect of layoffs because the tech industry is not immune to the downturn of the economy. >> silicon valley did a slick campaign making you think the industry cared about workers. it would give you a nice coffee, ping-pong table, stock options. but now when push comes to shove, i bet a lot of workers wish they had the power of previous generations to push back against the layoffs or push back against their employer, forcing to go back to the workspace. >> reporter: with these massive layoffs limit, kendall says she is definitely worried for twitter employees at the social media platforms and her friends use everyday. >> we rely -- so many of my friends rely on 24-hour news.

the potential to rattle the committees they are housed in. but this is somewhat of a unique situation here. many of the twitter employees have been working from home for the pandemic, which hit the market neighborhood pretty badly. when i spoke to matt dorsey, who is, again, his district is home to twitter headquarters, he told me while he doesn't wish layoffs upon any company , the in person policy could be good for the neighborhood. >> from the standpoint of the city and what it means for the neighborhood i represent, our interest is making sure that people are coming back to work and shopping in our local stores and supporting our small businesses , like here at the market on market street. we want people coming back to work. and we have to do our part as a city, making sure we are keeping our streets safe . that's why public safety has been a big priority for me. we've got to do our part to bring people back, too. fingers crossed that whatever happens

with twitter , more people come back to work , and that will be good for all of us. >> reporter: dorsey almost totally that there is a statewide law that requires companies laying off 50 or more employees to notify the city. the city as of this evening has not received this warning from twitter . he said this policy is a place largely so the city can provide these workers with resources and job training they may need. he suggested many of the employees who may face layoffs look to the city's open jobs opportunities here in san francisco. >> and there are pictured you get a sense the mood around, as you were visually , sometimes you feel it. >> the coffee shop we were sitting in went out of business in the pandemic. matt mentioned that it was one of his favorite coffee shops in the city. but we are getting some information that there was an email sent out to put their employees today.
