Ethical Issues in Offices

A friend of mine was very nervous today because he wasn't dealt nicely by his manager. The error on his part was that he included another colleague in a specific email correspondence whom his manager didn't want him to. This lead me pondering over 'Professional Maturity' & 'Ethical Issues in different Organizations' hence I started re-calling my not so long 10 years professional career to compile the list of issues:1-Wrong Resource selection (wrong person for the right job) and dropping/ignoring the right one.
2-Favoritism (Nationalism / Languagism)
3-NoAppreciation & Encouragement
4-Back biting & Leg pulling
5-Gossips
6-Illogical Promotion
7-Non-uniform task assignment to employee.
8-Mismanagement in Training & Skill polishing
9-Rough and tough behavior by managers in case of mistakes.
Here is some recommendations which need to be implemented for the corrective and preventive remedies:

-Ethical help lines should be available in companies. The process has to be completely neutral & private.
-Managerial level audits should be done by neutral staff in order to ensure that staff is treated neutrally and irrespective of favoritism.
-Mature employees should keep 'sniffing' the bad air in office in terms of gossips & backbiting and report to the relevant management for corrective and preventive measures.
-Reward & talent recognition system needs to be transparent.
-Promotions to be done based on actual Talent.
