Your post to gather information and docs from a premier institution, which is also termed as one of the most transparent, posted in the forum is interactive in nature.
Kindly update:
1. In LIC also is any time period is fixed for memorial, to start and to conclude.
How the companies or you have arrived at a reasonable time of six months. Is it stated in any of the rules that reasonable time is fixed as six months (for proceedings to start or to conclude).
A clear answer to this is imp. for your case also.
2. Likewise for sanction of leave.
In case leave is rejected then with in how much time the letter/inter office memo is to be supplied to the applicant. In case of rejection the letter/inter office memo to be supplied to the applicant is to be necessarily acknowledged by the applicant or not, and thus just a copy of the letter/inter office memo or acknowledged copy is to be maintained in record.
6. You had mentioned in your posts that no page number was assigned to matter placed on intranet, and later while your complaint was in progress, insertions were made apparently to cover and mask the wrongdoings.
It is believed that circulation of a hard copy of the policies is must.
Your queries are specific.
While it is universal wisdom that sense should prevail. It is noted from your posts that sense has not prevailed. The offenders have grouped, and seem to be adamant, and there is no order from top to offenders to stand and plead guilty.
