Career expert Michelle Goodman has written a handy article on how to determine if your job can be saved, or if it’s time to throw in the towel.  Michelle says that suffering from a chronic case of the Mondays doesn't necessarily mean you should dust off your resume and start looking for greener pastures.  Some workplace woes are fixable. The trick is knowing which ones and how to mend them.  Here are four scenarios to consider:

• The magic is gone:  So you've been at your job a couple years and now you're bored.  Instead of pissing and moaning, says Cynthia Shapiro, author of Corporate Confidential: 50 Secrets Your Company Doesn't Want You to Know -- And What to Do About Them, try to tap into what you originally appreciated about your gig and company.  If you come up empty, take a long, hard look at your job: Has it changed for the worse since you started? Has the company? Have you changed, perhaps outgrowing the work? If the answer's yes to any of these, it's indeed time fly like the wind.

• “I think my boss hates me” syndrome:  What if you are doing a heckuva job, only to be snubbed when your boss hands out the plum projects, pay raises, and promotions?  If no matter how hard you shine, you're ignored or sidelined by management, it's time to wake up and smell the pink slip. "That is not just job ennui," says Shapiro.  "That is danger -- you're in the exit lane."

• The Titanic is sinking:  When the company's in trouble, your job is too. If you haven't been paid in three weeks or the CEO's starting to blog about how the company's willing to do anything to boost profitability (translation: layoffs ahead), make like the Lutz family in "The Amityville Horror" and get out now.

• Your health is failing:  "If you tell someone you're in an abusive relationship with a guy and he's making you physically ill, they're like, "Get out, get out,'" says Penelope Trunk, author of Brazen Careerist: The New Rules for Success.  "But if you tell them your job's making you sick, they say, 'I know, I hate my job too.'"  If Sunday night dread is costing you a small fortune in doctor's visits and prescription drugs, it's high time you got out of Dodge.

This is a terrific barometer, but I would like to add the caveat that if you are a chronic job-jumper and find yourself looking for a way out once again, you might want to do some soul searching.  A pattern of unsatisfying work experiences could mean that the problem lies not with the jobs or the companies, but with you.  Remember that you take yourself with you and think hard before you decide that it’s time to go.
