Every once in awhile someone tells me they were constructively discharged, so they want to sue. They’re surprised when I say, “For what?” That’s because there’s no such cause of action or claim. Just because you were constructively discharged, that doesn’t automatically equal a lawsuit any more than being fired equals a lawsuit.
Most courts are reluctant to find an employee was constructively discharged. The standard is usually that no reasonable employee would have tolerated the conditions of employment. For instance, I’ve seen sexual harassment cases as extreme as rape that weren’t found to have been so intolerable that the circumstances constituted constructive discharge by the employer.
For unemployment purposes, if the company cuts your pay, changes your job duties in a major way, changes your shift, transfers you to a new location, that may be enough to be deemed cause attributable to the employer. But you’d better be sure before you quit if you want to make sure you’ll qualify for unemployment. Sometimes the unemployment office will have a website or have someone you can call to get information. Otherwise, you’ll probably want to be sure of your rights before you quit.
If your working conditions are intolerable due to discrimination, sexual harassment, failure to pay wages, or something protected by law, complain to HR in writing before you quit and give the company a chance to correct the situation.
My exception to the don’t-quit-unless-you-have-another-job rule would be if the work situation is dangerous (rape, assault, unsafe conditions). If that’s the case, then get the heck out of there. No lawsuit or potential suit is worth your safety.
