The rising gas prices have caused financial strain on US workers who rely on driving for work, particularly those who rely heavily on it. Leslie Sherman-Shafer, an Uber driver in the San Francisco Bay Area, has spent closer to $40 per shift since the Iran war began and pushed up the average U.S. price for a gallon of regular gasoline by $1. The national average price for gas reached $3.99 per gallon on Monday, up 34% from a month earlier, according to AAA. Some companies compensate employees for using their own vehicles, but this money is not going as far as expected due to high gas prices. The owner of Doggy Lama Pet Care Inc. in Oakland, California, recently raised her gas reimbursement rate to 80 cents per mile for 15 employees who use their own cars to pick up dogs and take them for hikes around the Bay Area.
