my principal told me to discontinue articleship from immediate effect



2nd year of my articleship will get over by the end of August 2014 and my final CA attempt falls in May 2015.. on account of ill health i was not able to attend my principals office for 6 days during July 2014 that is this month.. and today that is on 31st july i got a call from him telling me that i should not go on duty henceforth.. and that he wants me to quit his CA firm from tomorrow. can he do so?? i dont want to terminate my articleship because i dont want to postpone my Final CA Attempt.. on what grounds can he remove me? is there any way i can take a transfer.. i cannot take it on medical grounds as i wasnt ill for more than 10 days.. nor my parents have got any transfer outside the city .. please help! :(
