ZoomerZ,
I am suspicious as I think they don't want people yelling at them if extention will be cut...
If you need the extension now, and they say there is no one, then there is no extension, and they are not allowed to bend the law whether they like it or not. They are the state employees, who can very easily loose their jobs, which is worse than to be yelled at, you know.
If you are just asking for the future, what is the current law/rule, may be not in use any longer when the time comes, and you will have to ask when you need it. But I don't think you are in the beginning of your 26 weeks and just plannig to stay there all of them and more doing nothing, right?
In any case, I would tend to believe the people who work there. If you think the clerical worker who talked to you are not the most competent person there, ask for a supervisor/manager.
You can always request from them a brochure with the rules, they should give/send one to you, as you are their client and have the right to know your rights.
And of course, you can check their official site. I would look for Department of Employment in Pennsylvania.
