Is your current job making you fat? How can you reverse the situation without having to leave the position? A new CareerBuilder survey finds that 57% of the nation’s workforce believe they are overweight, and 45% believe they’ve gained weight at their present job, on par with last year. Twenty-six percent of all workers said they gained more than 10 pounds at their current job; 1 in 10 (11%) gained more than 20 pounds.
