Hi, I was working in a private limited company. I was selected and appointed as a cashier on a probationary period for six months but was given the duties of delivery of currency for which I had to roam from here and there with a large amount of currency. I was not even covered under insurance for doing this job. I was not permanent, and I left the job without intimation after the completion of six months. Now, my boss has sent me a registered letter and said that I have to pay one month's salary to them. So please tell me, do I have to "sign" on the registered letter or not? Even they did not mention in the appointment letter that I have to pay one month's salary if I leave the job without intimation. Please reply to my email ID, i.e., mak_0410@yahoo.com.
