Dear Sir,

I am writing this letter to inform you of my resignation effective from 1st November 2014.I have experienced a great time here at Alexion Pharmaceuticals where I have learned many things; the value of time and value of hard work and acquired self-motivating skills. I actually learned how to work in the team and how to blend with team members. But unfortunately my reason for resignation is I want to continue my further studies so I grabbed this hardest decision of quitting my designation. I can continue working at Alexion Pharmaceuticals simultaneously I can continue my studies as well but In order to focus only on studies I have decided to go back to school. I have extremely enjoyed my work time at Alexion Pharmaceuticals.

I wanted to thank every member of my team, colleagues and you for the great maintenance of company and I appreciate you and Alexion Pharmaceuticals for good days ahead.

Sincere thanks for the support,

Best regards,
Yours faithfully,
Litchis
