Anyone who doesn't think Wall Street has an impact on your job, doesn't know wall street. Companies release financial results. If those results are below what wall street was expecting, or if there worse than expected, wall street and investors are not happy, and the stock price tumbles. Company then responds with cost cutting measures to get things under control and please wall street and investors. It's in those "cost cutting measures" that your job could be in jeopardy.
Case in point... After yesterday's disastrous financial report from Walgreens, the company responded by saying in part, that they will close some stores, as part of cost cutting measures, to get their financial house in order. If you happen to work in one of those stores slated for closure, then your job is in trouble, if they don't offer you a position in another store or elsewhere in the company. So YES wall street can definitely have an impact on your job. And the lower the stock price gets the greater the cutbacks, as a company will dump almost anything in an effort to try to stay afloat. Just look at Rite Aid... They just fired 3 of their top execs, including the CEO! And store closures for rite aid is not off the table either.
