The workers say they've been dealing with uncertainty since their last contract expired in December 2009 and that's affecting patient care.
Radiation therapist Amanda Reid says they've offered to give up the right to strike if the government will bring in independent binding arbitration.
Health Minister Don McMorris was asked about binding arbitration during question period in the legislature, but did not address that issue directly.
McMorris says negotiations are between the Saskatchewan Association of Health Organizations on behalf of the cancer agency and the union.
He says he hopes to see a deal soon.
