No, unless there is a written employment contract guarantying you transportion, your employer is free to change the terms and conditions of employment at any time, such as by eliminating transportion and they could then terminate you for abandoning your job if you can't get there. They also could have simply terminated you right away if they wanted, wthout first eliminating the transporation that is because without a written employment contract, you were an employee at will and as such, your job could be changed or eliminated at any time, for any reason, without prior noticing.
