Am I Really Liable for Notice Pay After Being Terminated Due to a Schedule Mix-Up?

Dear all, I was terminated by my company because I did not report for work after they changed my schedule. I was supposedly on OFF days and wasn't aware that it had been changed to admin duties. They did send me an email about the change; however, I was away because I was on OFF days and without internet service, so I was again unaware of the emails. It was only after I reached back home that I saw the email stating the letter of termination of employment by my company. I called HR and was told that I have to prepare approximately $800 to pay the company because I was terminated and failed to pay the "notice pay."

Question About Liability for Notice Pay

My question is, am I liable to pay the company? My contract did not mention that the 'notice pay' is equivalent to one whole month of basic salary. Please help to answer my doubts. Thank you very much!!!

Dear Company has terminated your salary without notice, so they will be requiring to pay notice pay in lieu of notice. If one day you have not reported for duty, how can they terminate your services? It is illegal, and they need to pay you one month's basic salary as notice pay as per the terms and conditions of appointment.

How many off days did you have?

It appears to be rather harsh that they gave instant termination orders without even giving you a chance to answer or clarify. If that be the case, the company has failed to follow procedures for termination. You are supposed to be given a chance to explain the absence or misconduct, etc. One-sided dismissals will be held bad in law.
