I received a "final warning" for not following the code of conduct. I have a proven productive track record with the company for over 15 years with positive annual performance appraisals. I advised management that a new position was required in the company to oversee junior staff. when the position was created, I applied. In the interview, the hiring manager advised of the names of the two other colleagues that applied and asked "what would you do if you do not get the job?" I was also asked how I would improve the team (scenario questions). I discussed how I would go about bringing up the the other two staff (that applied) and I had mentored when they were hired. 4 weeks passed and I followed up, and then I received a meeting with the hiring manager and HR to advise that I was disqualified based on code of conduct issues for asking another employee to call and make a recommendation for the job and for putting down the other two candidates in the interview. I then received a "final warning letter" and was advised if I spoke to another employee or did not follow the letter, I would be dismissed.
