If it has a "path to citizenship", it ain't a "guest worker program"---just another way to get "amnesty" one piece at a time.
As I recall it would do a lot more than that. It would allow illegals who obtain a permit (i.e. the "Z visa" in the last incarnation) to qualify for welfare benefits in five years--prior to becoming citizens. It would provide them with taxpayer-funded lawyers and job protections Americans don't have (couldn't be fired except for cause). And in the event of firing, taxpayers would foot the bill for mediation.
Also, should the illegal die leaving minor children, there was a provision for Social Security benefits.
