In this instance, you, as an employee, are in a better position than most of the employer’s creditors. Employees are considered “secured creditors” under bankruptcy law, and are therefore given priority if they are owed unpaid wages. The bankruptcy court supervising the bankruptcy will decide who gets paid what out of the employer’s remaining assets, and unpaid employees are among the first people to get paid. Be sure to contact the Connecticut Department of Labor and file a “statement of claim for wages” if you are owed money. (This is a good idea any time you are owed money.)
If you have a retirement plan with the company, the plan can be terminated, and accrued benefits may be paid out. Read more here: United States Department of Labor Fact Sheet
The IRS has special rules regarding income reporting for employees whose employer goes out of business, too. Read more on the United States Department of Labor website.
Your unemployment benefits should not be affected by the employer’s bankruptcy, since this money does not come directly from the employer.
