I have been working at a store for 7 years, another employee asked me to cove the shift for him over the weekend and possibly on Tuesday but he would let me know if he actually needed me to do so. I worked on Saturday for him and did not hear from him at all. When I came to work on Tuesday I found out that nobody open the store in the morning. The owner standing at the door told me that he was giving me 2 weeks notice because of what happened. Can I file a claim against him? is this wrongful dismissal? Should I file a claim with the human rights tribunal? Please let me know
