HR removed him from his company's Whatsapp group

One of my friend is facing a big problem, suddenly one day his HR removed him from his company's Whatsapp group. Next day when he asked about that he was told that he will get mail. His salary is on hold for the month of May and his expenses also on hold for April and May month. Hr and seniors completely ignoring him.
Kindly suggest some solution.

Dear friend,
By reading the heading of the post, one feels that the HR was removed from the WhatsApp group or what. Nevertheless, on reading the post one gets a clarity.
When the person was removing from the WA group, it showed that he had become persona non grata. However, before withholding his salary, HR should have communicated clearly what was the reason for holding the salary. Anyway, as of now, let that employee put up application to the Director or MD of the company seeking clarification. That is the first step.
Thanks,

What is the position your friend holds in the company?
Is the Whatsup group official group?
Your friend needs to meet HR and find out what is going on?
Putting things in writing would be the next course of action after meeting HR people and his HOD.

Dear Colleague,
It is obvious that such sudden actions point Howards what is waiting in the wings for you.
Before axe falls on you, try to find out what has gone wrong and if it is unjust intention on the part of the management, take up with the right authority to resolve this before it is too late.

Ask your friend to lodge a complaint under payment of wages act before the labour authority of that area where he is working as an immidiate action.
