Today , i got a telphone from my former boss . He said that his business will be very busy this year and hoped me can back to his company . He ever told my former manager let me back , but i didn't ! Just this time , he called me himself . I have thinked about it , i decide to back . There were three factors make me do this . First , the boss treat me very well , i am very appreciate him . Second , i have to go to Sha Jing to study every week ; present company is very far to the location of my study , it need take me one hour go there , that is meaning i need get up at least 7: 30 am , it is so early and on sunday ; but former company near the location . Third , present job is so free that i can't get any exercise , i think my work just obey the order and no any right of lead , but there i can lead my work and arrange it by myself . The third factor is the most primary . I will submit a resignation to my manager tomorrow . This decision will be a important change . I hope my change is right .
