Businesses that establish credit cards in their employees names, create an authorized user situation.

Meaning that both the employer and the employee maybe liable for the charges.

This can be good or bad.

If the company pays the charges every month, those timely payments maybe reflected on your credit report.

However, if the company fails or closes, the employees maybe left holding the debt.

It all depends on how the bank opened the account.  If you have questions regarding your particular credit card, first ask your employer if they know -- most likely they won't.  Then you can call the bank and ask what your liability might be.
