Companies that consistently delay salary payments every month are not considered normal or ideal. Punctual and regular payment of salaries is an important aspect of employee satisfaction and indicates a company's financial stability. It is concerning that the company you have recently joined has delayed salary payments for the past three months, even up to a week. The fact that they have no concept of adhering to a set payday is worrisome. While it is possible that the company may still eventually pay the salaries, such recurring delays can indicate underlying financial issues or mismanagement. If you are experiencing such delays, it is prudent to be cautious and consider any potential problems the company may have. If you are still within your probation period and are uncomfortable with these irregularities, it may be wise to explore other job opportunities that provide more financial stability and better payment practices.
