You have posted that:
--“our Sales Incentive Payouts the mail mentioned that I need to wait till the end of next quarter for the SIP (June end) “.
The incentive is obviously for the period Jan-Mar.
“Finally I left on 16th April,”
If you have worked for the entire period, of the incentive qualifying period i.e. Jan-Mar then nothing is pending from this period.
“I wrote to my ex supervisor and after 100's of unattended calls and a few emails later he told me that it is being withheld as I did not complete a assignment.”
The assignment being quoted as not done is probably from period after March. Moreover your communication is in writing and reply of your supervisor is probably verbal.
It may be the internal practice of the company to give the discretion to supervisor to block or allow the payment; however the authority to sanction disbursement is the one who has issued the incentive circular and/or who is stated to be final authority in incentive circular. Do you have the copy of incentive circular?
You may decline to be satisfied by verbal responses and demand all replies in writing.
You may claim that you never left any assignment incomplete during the period Jan-Mar.
--“I have written to the HR who said that my immediate supervisor had requested the payment to be held till he authorises the release.”
Once again your communication is in writing and reply of your HR is probably verbal.
Employee should record such transactions {audio/visual} and keep some witness/evidence.
Another option is if deemed fit at your end you can claim to HR that you left nothing pending from Jan-Mar and even later.
If employee has tendered notice of resignation of say……45 days, i.e. last day in office/effective date of resignation is informed by employee and company has received/acknowledged/processed the notice then company has to coordinate well amongst all dept’s and ensure that all exit formalities including tasks to be obtained from employee are completed. You have tendered reasonably good and long notice period of 45 days.
“post resignation I did get my Full and Final settlement.” FNF settlement is done post completion of all formalities and clearance by all dept’s/HOD/line management etc.
To whom you have handed over the charge and who has cleared the handing over of charge? Ideally your supervisor should have signed the handing over the charge. Did he mention any pendencies? Had he mentioned any pendency your NOC would have not been issued for conducting FNF. Did you receive FNF statement? If yes you can claim that nothing was pending at your end and FNF statement and settlement was issued post all clearances.
To whom you have handed over the company property? Usually the form of submission of company property has scope and column for remarks by authorized supervisor/HOD to record comments of pendencies if any. Has your supervisor or HR communicated any pendency in writing?
Incentives are paid after all returns/collections/payouts are computed and effected and eligibility has been passed.
Bonus {Statutory} is paid within 8 months of ending of previous year bonus period.
Company has to pay all eligible amounts. If company has to deny any payment it has to do so in writing and enclose certified copies of all relevant circulars, clauses.
HR does not report to line management. HR should remain unbiased. If you are not getting any relief you any approach good offices of your appointing authority, MD, Chairman, Company Secretary.
--“ (this is pure harrassment as I had paid for the equipment and dont have to return it)’
Do you have the proof of payment?
You may state by return reply that you have paid for it and hence it is your property and company should issue you a certificate of ownership in your name and if company wants it back company may state so in writing and offer to buy it.
Most probably the payment made by you has not been computed.
If you wish you can ask the company to beg apology in writing for threatening you and/or defaming you.
--You may find the attachments as useful.
“Allowances covered in wages” .As per definition, the sales commission should be paid within 2 months
{ANNUAL COMMISSION}, {INCENTIVE BONUS}
And
Appointment letter Law of negative covenants in employment contract
{Are Increments automatic or linked to performance? Incentives and Performance linked payments}
--If you feel it is OK you should help the supervisor and company to complete the assignment being shown as pending {from customer’s end}.
In a given situation employee can invoke the Industrial Employment standing orders Act, Payment of Wages Act, SE Act, and ID Act as per explanation of employee under these Enactments or approach civil court.
