PIP is initiated by the management or probably by your supervisor. It is a very structured monitoring process of under performed employee.
Reason is depend pretty much on the mercy of your employer or how much that troublesome employee is willing to commit to do all the necessary action item within a time frame, usually 3 months.

After 3 months the result would be reviewed, and to decide whether to terminate the employee, extend PIP or deactivate the program.

I have read my company's policy regarding PIP:

Termination due to performance

An employee who is not able to perform his/her work satisfactorily shall be informed of his/her weaknesses by the line manager who will set measurable targets for specific areas where improvements are expected.

If these targets are not met and the employee's work performance does not improve after an agreed review period and after prior counseling have been given by the line manager, the services of the employee shall be terminated.

I guess if line manager fail me after PIP means kena fire liao.   

It's a long story, and it's a unique one just because i am different species in this industry which mostly dominated by men.
I had a fair share of harassment but i cant say a word just because he's a manager (very skillfull but asshole attitude).
Been transferred to different department, i was happy for a while and the cycle repeats again. I once was assigned working night shift for almost a year without any competent person. I was by myself doing all of the reports and making a lot of mistakes. But when i raised my concern nobody gives a fuck. I feel demoralized and sad, and became defensive with everyone. My latest manager not sure how to approach me & straight gives me PIP due to my last year poor review. I knew it will eventually leading to this, i dont know what to do at first. but then maybe this is the right time to prove myself that i am worthy, it's just communication breakdown. The good thing is during the 3 months i am entitled to use all the counseling benefit and travel for courses. I have to work hard both during my shift & attending courses during my off days. and of course keeping reports. No doubt the program changes me to a new person though. Well i dont really care if i made it or not in the end, at least i close the gap and they see me as trying to improve myself. Once you're out of this, this is the biggest takeaway you can do for yourself.

The PIP is ridiculous even if I do all they will still fail me. What is the next course of action will they take? If they fire me that will be very difficult to find next job is it? Reason for leaving previous company kena fired. Or they will not mentioned if my new employer called HR? Or if I join company under different department will there be problemin future

Or should I resign before they fire? Need to know how long I have to find a job?

PS there is no signature whether I agree or disagree to this PIP or I have no say

Performance improvement plan, or personal improvement plan are nothing good to begin with.
Once a person enter this shit, when a particular company want to restructure manpower, he/she will be the first to go.
By right, for a person to enter this, he/she must be really cannot perform and always have problem with the boss. But sometimes is more on because the PLP skills are not good.

they dont need any signature, as long as you get from email stating your PIP will start at this date to date..then it's official.
if you have not secured anything good yet, just hang on & play their game. 3-4 months salary plus overtime & allowance and benefit is good for now rather than 'mutual separation' package which only paid basic until at the end of the year.

my company have 3 stages of PIP, first one counseling, 2nd one verbal warning & 3rd written warning for duration of 3 months. if the company is hell bent to terminate you after the last warning stage, look it this way..9 months of full salary is better but then fired maybe no compensation..

your choice.

Yes, i can feel that.

In my opinion best monitoring 1 year's + 3 months.

If within a year you must at least score your kRA 50% then should be fair enough, if you're really in your effort. 50% should be okay ler.

Question to yourself :- Challenge yourself rather than others - Gain Victory. - ( i been through this and it works but really will turn you crazy) - stress. - not recommended haha.

Incentive base is solely base on your hardworking not free.

But company insist with pip - indirect filtering than is fate la.

Question : Have you done the best ? If yes, that's still the decision given. fate.

Try others & skill and knowledge always with you.

Find a place where there treasure you.

It wont be good for them if turn around to high. - Gods know
It may happen in may point of view.

* May be related to as what speedfamgirl mention " between manager & employee
* System of the company :- accurate ?
* Turn around time " efficient ? done within a day ?
* procedure ?
* empowerment to all your staff, cut of the time.
* to be equally divide if so call free token.
* team work and helping each another is the key.
* without your manager support & trustee will cause all good to bad.

Before pip was done to employee will the upper level being serve the same ? - major answer "no" .

Sometimes i feel weird as there keep stressing their staff and why not questioning their hod whether are there fit to be there ?

Or there were set there because of education ? degree and so. where he only good on manipulating the management part,

Question / Answer from upper path direct to your staff to solve.

If that's so, not bad considering to be a manager which 9-5 on time.

Only by instructing his staff to be frontier - fighting day and night.

Which field were you from in your past ?

Before a PIP is implemented for an employee, will upper management go through the same process? The short answer is 'no.'"
