No, unless a company releases new stock options that are diluting the value of the current shareholders, the money doesn't go to the company, it goes to the shareholders that sell the shares. Their money doesn't create employment, it realises the capital gain of other investors. And companies don't want to dilute the shares as their sole purpose is to increase shareholder value. And even though they sometimes do, it's pale in comparison to stock buybacks which are exactly the opposites, removing money that could be used for R&D or for workers and raising the imaginary value of their company by inflating investors shares.
