Good evening sir. This is Saibal Chakraborty. Area Manager of Strathspey Labs Pvt Ltd. You know me better for CLIRNET SERVICES. I visited you many times. Sir, today I am sending this message not for any professional reasons. Actually sir in spite of a permanent employee of STRATHSPEY LABS , company Terminated me on 6th of February 2017 all on a sudden without any reason. Anshul Agarwal (Exe. Director) , Montu Kumar Das (ZSM) , Shantanu Manna (NMM) , Raja Paul (Sr.Mgr-CLIRNET) all were presented when i went office. All of them were the part of this. I requested several times, but all were in vain . I am from a very much middle class family. Live in a rented house at Dumdum. My father is 76 years old and very much sick. Any thing may happen with him anytime. My daughter is only 10 years old. And i am jobless now . Now I am 40 + . It is very very tough for me to get a new job at this age. Because of that incidence , me & my entire family now under tremendous mental & physical disposition. Don't know how to live & run my family . In this situation if possible, please help me to over come the crisis . This is a humble request from the core of my heart , from the core of a father's heart to all of you. Please. ........
