Это не письмо-жалоба,а письмо-извещение т.к человек не может выйти на роботу и объясняет почему.Dear Mr.Rickard,I appologize for emailing you so late.I want to inform you that unfortunately,I will not be able to come on time this Friday.The reason for my lateness is contingency. I have just found out that my grandmother has died today.She used to be very important for my family and this is definitely going to be a tough time for all of us. To be honest I do not feel that I can really concentrate on work at the moment.May I please ask you to allow me not to come this Friday as I have to organize funeral service and I need to support relatives,especially my grandfather. I do understand that it is not a good beginning of my new job on such a responsible position,but I can assure you that I am a very responsible and punctual worker. If it is possible I would rather stay longer one day next week complete the work which I will miss on Friday?Thank you for your understanding.Yours faithfully,John Price
