The union representing college teachers sending members an email saying its time to prepare for strike action.
OPSEU officials say their bargaining team tabled an offer yesterday morning and the College Council refused to engage on any of the key issues.
Among the union demands, college's establish a 50/50 ratio between full and part time faculty, strenghten job security for part timers, as well as form a joint task force to establish academic senates by the end of the contract.
The union adding teachers will not be in a position to strike until the week following Thanksgiving at the earliest.
It adds they do remain committed to negotiating a fair deal with strike action only being a last resort.
