Put on performance improvment plan
I've been put on a 60 day performance improvement plan for not applying job knowledge, inaccuracy and work accountability. I responded to the plan stating that I've been giving it a 110% and pointed out why I'm a satisfactory employee and also sent letter to coworker stating I'm trying to improve. I've stated numerous reasons why i thought the plan was vague and unfair. If I'm let go what can i do to protect myself and what do you think are the possibilities of getting UI?
You are taking the steps now. Counter documenting is what you need to continue to do.
Just because an employer starts an improvement plan .. doesn't mean you won't get benefits, although the reasons you said the employer is using would be the suggested course for a good case against benefits.
It all sounds like neglect to perform the duties to the employer's expectation .. and not because of any inability.
I can't say what your chances are.
I hardly have enough information to judge.
