Hedge fund manager Bill Ackman on Monday took more swipes at Herbalife, saying he has not changed his highly-publicized bet against the nutritional company.

"If you find yourself as an Herbalife employee today, my advice is that you should leave the company because this is not going to be a good thing on your resume. I'd go find another job," the Pershing Square Capital Management CEO said on CNBC's "Fast Money: Halftime Report."
