I have been employed for almost 12 years at my current company. I recently have been diagnosed with a sleep disorder and due to that, I took a leave of absence from work and went on EI (sickness benefits). I was informed today that everyone at my workplace received their Christmas bonus (which we have been getting for all the years I have been employed) but I did not get anything. During the last year of my employment I was also discriminated against due to my illness which contributed to my stress and made my condition worse. I am wondering if this is a case for constructive dismissal and what my next steps should be.

Thank you
