Did I mention this "other guy" is my bosses son-in-law of 2 months??
That'* why HE got the raise
Can you say "Conflict of interest".
Step 1 - Explore the local job market and position yourself for a job move
Step 2 - Book off sick for stress leave from your present job
Step 3 - Sue for loss of wages, pain and suffering due to his blatant conflict of interest.
Step 4 - You will get a very good severance package $$$$
Yes I'm joking but if you're serious, it'* an open and shut case.
