Colorado is a right to work state and has no guarantee of employment. Depending on the amount of employees the employer doesn't or may not even have to keep someones job available for a maternity leave. It sucks, but it helps small business remain in business.
Wait to see how all these new Obamacare requirements change employment. In small business it is gonna be tough to get a full time employment at all because of the requirement of health coverage.
I wouldn't be surprised if many small business cut all employees to part time.
