I have been with my employer for 2 years. I drive a truck delivering ice cream to grocery aand variety stores. In the summer i average 50 hours per week and in the winter 40 hours. A couple of weeks ago my boss asked me to start doing a different route whic involved an auto tailgate and the use of a power jack. I informed him that i was not comfortable doing this without the proper training so he took 5 minutes to show me. I aagreed to do it but told him i was still uncomfortable doing it. I arrived at my first stop the next morning and proceeded to unload the product. I felt very uncomfortable and unsafe. I sent him a text telling him just that. When i arrived back at the warehouse i was told there was no work for me the next day and he would inform me when there was work. I only worked 10 hours that week and 9 the following. I haven't been called back since last tuesday. I am a 53 year old male and a type 1 diabetic as he is well aware. I now have not been able to pay my rent this month or been able to afford my insulin and supplies as i had no notice that i would be losing all my hours. Your advice would be greatly appreciated.
