Employee Departure Without Notice
Even if no appointment or offer letter is issued to the employee, if the employee is guilty of lying and leaving the company without intimation or on very short notice, and it is proven that they joined another company for better prospects, the employee, being absconding or leaving on short notice, causing damage to the previous employer due to sudden and abrupt job departure, cannot ask for their salary. They are already being compensated by the new employer benefiting from the employment. The previous employer, within their rights, can refuse to pay their salary.
Due to this unethical poaching, some organizations pay salaries after the 10th of every month, allowing employees to collect the salary for the previous month but forfeiting the salaries of the first 10 days of the current month as compensation for leaving without notice or abruptly. The employee then has no rights to claim the salary for the 10 days, having abandoned the employer.
