I worked in this company and the work process is good by the time of salary it comes in next month in the date of 15-20 in working days for that process also it may delay for some times and they will hold the salary its the rule i agree but the thing is they hold the salary of last month also which i have worked when the salary will get next month that time i took 3
Days leave which i have intimated to my tl also and if they want to hold the salary also they can hold of that current month that which i took leave of that current month then why they sucks hold of my last month salary is that any rule which i worked they didn't pay is that a rule of they will hold salary the company hire employees but they cannot afford the correct salary for an agent which they worked of that month it's really sucks when we ask the salary they just giving silly reasons
