Good Afternoon Peter so in this workplace i am in after training i was promised to get a permanent job since i did well and got the feedback then i later on waited another full month only working as a casual and going to work only if i am called too...just last week i when i was called i went as usual and i apperently fell sick the next day and when i called my manager to inform him he dismissed me out of the workplace and was busy promising me his going to cancel my contract i tried asking him for a solid reason and he never answered me.
