Life is all about choices and consequences.
"For every action, there is an equal and opposite reaction." -Albert Einstein
Some people try hard and give their best with no other intention than to be helpful while developing themselves. They simply refuse to stop reaching their full potential and expanding and growing.
Often time they were misunderstood as trying to show off when they genuinely felt responsible about giving back to those who gave them the opportunity, taught them things and made them the person they are now.
While people misunderstand their efforts and principles, they struggle with being stuck between 2 choices: to keep their values & principles or to work in a so-so manner, stop giving extra effort but liked by others. The latter would lead them to a life full of guilt and self disappointments.
And our action can determine their reaction.
Think positively; some people live their lives to the fullest to avoid regret later. Let them be, and don't change them. Don't make things hard for the people who try to ease things for you.
And for you, think about when you are the happiest working despite the challenges. Return to that path, and stay on it. It's hard and lonely, but it comes with barakah and self-fulfilment. But when the environment causes you to contemplate right and wrong, or to the extent where you feel that it would be better that you are not around, leave. Don't stay when your self-esteem might be destroyed in the process of being considerate.
And for the employer, don't close your eyes just because you don't want to go against the majority. You are not a politician. Don't play safe. Trust me, when your employee leaves, they hold the most grudge on you instead of the colleagues who mistreated them.
