Salary delay every month - we haven't received our February salary till now

Hey, I have been working for last 4 months with this company and we were told that the salary cycle of this company is 15 - 20 and after joining we got to know that the salaries are paid at the end of the month or after that every time. I joined this company on 15th Jan and till now only salary of first 15 days of Jan had been credited. I wanted to ask is this ok? Because most of would have received there March's salary till now or they would be getting it in some days but we haven't received our febs salary till now.

Obviously this delayed cycle is not ok.
Is the cash flow of the company slow ir irregular?
One needs to know
As such signs of delayed salaries contrary to law is an indication of a weak company or a poor management. Either you should read the signs and accirdingly look around for alternative jobs.
Are you fully engaged with work or there are times when there is no work.
Analyse carefully n look for opportunities elsewhete in discreet fashion as jobs are scarce.
Meanwhile upgrade skills knowledge etc

Yes I think cash flow can be slow as the company is a channel partner in real estate but my concern is getting our salary late everytime isn't ok so what can we do? Like any legal action against them?

Can anyone tell me? Can I sue this company?
