A recent report from the investment management company BlackRock warned that a worldwide recession unlike any other is now just around the corner.The grim economic outlook has caused employee concerns about layoffs to skyrocket, Lauren Thomas, a UK-based economist for Glassdoor told Insider. She said that on the company review website, "October mentions of layoffs doubled, discussion of inflation tripled, and talk of recession increased nearly tenfold from last October. "Workers have been wary about how an economic downturn may affect their employment opportunities for some time. This summer, almost 80% of US workers surveyed by Insight Global said they were worried about losing their employment if the country entered another recession. While a truly recession-proof job is elusive, some industries are typically safer than others. Most at-risk jobsTech jobs Courtesy of ShelterTech After a pandemic-inspired hiring boom, layoffs have been spreading across the tech sector in recent months, with major job cuts hitting tech giants such as Meta, Twitter, and Amazon.Tech companies are suffering an early economic hit sparked, in part, by a slowdown in online ad spending.However, Glassdoor's Thomas says those in tech with highly specialized skills are still largely in demand across the board, and will likely be rehired quickly if they are laid off.

E-commerce and social mediaExperts are already starting to see a drop in demand for some digital-facing roles post-pandemic. "Pandemic-induced demand for certain technologies like e-commerce or social media has fallen in the past year," Glassdoor's Thomas said, as e-commerce and social-media jobs rea affected by a change in consumer demand following the COVID-19 pandemic that forced much of marketing and shopping online.She said "while the fundamentals of the industry are strong," companies that are still adjusting to the new post-pandemic normal may see a slight downturn in the short term.The most recession-proof jobsHealthcare Getty Images Professionals who have the most job security in a recession include doctors, physicians, and nurses but also, for example, pharmacists, physiotherapists, or carers for the elderly and disabled, Bartosz Sawicki told Insider.Sawicki, a market analyst at currency fintech Conotoxia and macroeconomic forecaster, said the same was true for veterinarians, "as we care more and more for our dogs, cats, and other pets as our civilization develops." Public safety and social services A Met Police officer Getty Images Public safety and social services jobs "tend to remain stable and sometimes even grow during recessions as governments spend more on programs like job seeker-training to stabilize downturns," LinkedIn's Kantenga said. These roles include governmental positions, law enforcement officers, firefighters, emergency medical technicians, correctional officers, security guards, and occupational health and safety specialists. "Withdrawing government, educational, and health and social services in a recession is generally unpopular," he added.
