Looking into last post of the querist;
The order of termination is speaking order. Without opportunity of hearing/ natural justice the order of termination (speaking) can be termed bad order.
Asking employee verbally not to attend office or blocking access etc can be termed ‘Deemed Termination’.
In such cases compensation/notice pay/damages may get fastened on employer.
It is upto the querist to accept or decline to accept verbal order of termination and agitate.
The employer after resorting to verbal termination (that may be good for nothing) can also pay FnF dues/Gratuity in a/c of employee or by cheque. Mere supplying such payouts may not necessarily amount to acceptance of termination. Employee can return/refund such payouts on his/her own or per order by Authority/Tribunal/Court of Law.
If employee is made to work on holidays (paid holidays) employer is under obligation to tender OT, compensatory off.
Employee can agitate on these grounds also.
