You have not replied to all points, pointwise.
But you are posting frequent queries!
You are converting the thread in chatting and it won't lead you anywhere.
Hope you shall take the posts in positive spirit.
The ill informed, non united, unorganised employees are a sittick duck and succeptible to exploitation, harassment.
There are set and section of employee's that have always ran away from forums/unions during school. college time, while in employment, and remain ill informed and are easily targeted by high headed, arm chair managers.
You have posted that:
"I have served 30 days of Notice period from the day I have submitted my resignation and I have paid 1 Month Complete Salary as demanded by HR team.
My Manager said that he needs some work to be done later he will give relieving letter, as I agreed I have supported them more then a Month after relieving and I have completed the task."
Thus as per your own post you have tendered notice of resignation, paid for shortfall in notice pay duly calculated and demanded by your designation attorney of employer i.e HR personnel, even succumbed to unfair demand of working for 30 days after LWD and completed tasks assigned after LWD, and completed such tasks as well.
Look you have been asked to work after tendering notice pay and LWD accepted by employer's attorny...................
Reliving letter signifies that employee has separated, nothing is due against employee.
Moresoover as per your own posts this Manager is in CC of all emails.
Still the manager has the nerve to state in WRITING that you are not relieved.
Either the manager is acting as per unwritten/written polcieis of employer that are not shared with you OR by his own stubborn, arrogant attitude.
You may look into Tamilnadu Shops & Estbs Act:
The notice period may not be more than 30days.
You may look into Tamilnadu Shops & Estbs Rules;
The employer has to submit Form'N', that you can obtain from Inspector appointed under the Act or thru RTI.
The employees in Tamilnadu united against TCS and affilliated with trade Unions, and rest is history.
The employees in Karnataka united and affilliated with trade Unions, and rest is history.
You will find the list of trade unions on website of Dept. of Labor Karnataka.
if you are unable to resolve on your own, lean on your able counsel specializing in labor-service matters.
Are you aware of any counsel, that can support you at bangalore and Tamilnadu at the same time?
Do you want us to make some more, suggestions?
