I worked for a small business for just over 8 years in a senior management position. Over the course of the last three or four years, the principal has become progressively unpleasant. I was frozen out by the principal, had my remuneration reduced and my job description changed to a point that I could no longer work under his employ. I resigned on November 10th this year. It was agreed that I would work out the pay period which ended on November 20th. It was agreed that I could have a day off to attend a conference for professional development at my own cost. I have just received notification I did not put in a request for leave to attend the conference, as such my pay has been withheld. I should note that in April this year I worked every day for three weeks, including weekends and was then forced to take two days leave in order to visit my sister. Do I have a case for constructive dismissal? I thank you for your assistance in this matter.
