I was recently fired after my probationary period for a reason that was never brought to my attention and which is also untrue. Not only that, I was told a different reason for my termination than what was stated on my termination letter. Is there anything I can do about this? How do I go about claiming wrongful dismissal and what evidence would I need? I was told that the reason was because they did not want anymore part time employees so they hired a full time person to replace me ( without any notification of this) removed me from the schedule and fired me without notice.
