The use of "Er" as an abbreviation for "Engineer" is not a legally recognized or protected title in India.
Here's why:
* No legal recognition: The use of "Er" is not sanctioned by any regulatory body or act of Parliament in India.
* No professional entitlement: There's no legal framework or professional certification that grants engineers the right to use this abbreviation.
* Potential for misuse: Using the abbreviation could be misleading, as it may imply a level of qualification or recognition that is not actually held.
However, there are certain professional bodies and regulations that may govern the use of titles by engineers:
* The Institution of Engineers (India) (IEI) is a professional body for engineers in India. While they don't specifically mandate the use of "Er," they have their own rules and regulations for professional conduct and the use of titles.
* State-level engineering councils (like the Maharashtra Council of Engineers) may have specific rules regarding the use of titles, but these rules are not necessarily uniform across all states.
Therefore, while using "Er" is not illegal, it is not recommended. It's better to use your full professional designation (e.g., "B.Tech. (Civil Engineering)") or use your professional title (e.g., "Civil Engineer") in a formal setting.
