Should I tell my construction employer the real reason of my resignation?
Telling your construction employer the true reasons for your resignation should be done only if it not a subjective negative reason - such as I am moving closer to my parents or making a change of lifestyle and profession. Poor pay, poor advancement potential, difficult personnel and policies are subjective and will not likely be understood or agreed to by the employer.
The time to discuss your disagreements or subjective issues is while you are working with them so that a proper solution can be determined. After you have accepted another job offer and are committed to leaving is not a good time to vent or communicate anything subjective that can be interpreted as negative.
It is best to only communicate only upbeat, positive things during your resignation. Complement the firm and people who have provided you the job opportunity and who have helped you grow professionally. Even those you disagreed with can be helpful in your personal and professional growth so complimenting and showing appreciation will be well received.
You may encounter your previous construction employer once again in the future for whatever reason, so don’t give them a reason to disrespect you or resent you.
