A quick pause as we return to the OP's question -
Several colleagues of mine submitted letters of intent a month ago. Our FT supervisor has yet to complete any of our intial assessments.Not one of us. Other PT sups seem to have breezed thru(under Different FT sups), but of course not selected as of yet. Some of us have degrees, some military experiences, some even ran a business. The rumor is that FT Sups neglect to complete assessments as a way of denying promotion without outright saying "your not promotable", hoping you will simply forget about it. Another rumor is that the FT SUP, will delayed it untill he has unoffical approval from a higher manager, because HR takes over the process and it gets outta thier control. Finally, another rumor is that the FT Sup will undermine your promotion in order to avoid to being transferred to a "help needed" facility or simply He/she is too lazy to do it. My thing is, if selection is not guaranteed after passing the panel, why hold anyone up. What are some of the experiences you all have had?Whats is the cold-hearten truth?
When did you submit your letter of interest to HR? You referenced your colleagues, but not when you submitted your own letter.
Which process was this for? The MAPP or Sales Selection (BD) Process as how they are handled is completely different these days.
At the end of the day the Initial Assessment (IA) has to be completed, your FT Sup cannot just hold onto it indefinitely, although I can see a period of time that is longer than it should to get it complete, they have to complete it at some point and either approve you or deny you.
Yes, they do have to have the approval of the next level manager before the paperwork is submitted, but they would have already reviewed this with you more than likely.
Is there a particular position that you have been made aware of or that is posted on the Management Career Opportunities (MCO aka Job Board) that you are not able to be considered for because of the delay?
Have you talked with the Supervisor in question regarding your IA? Checked with HR to confirm receipt of the letter? Depending on the process that you are going through there are other steps that I would recommend
There are a lot of rumors that you mentioned in the OP, but not a lot of facts. It's not a perfect system, but it is a lot better than it used to be.
