Look for signs of mistrust:
First of all you need to find out whether you need to act or not. If people around you avoid communicating properly, have closed-off body language or they do not show warmth in relationships then there certainly is a lack of trust. This means you really need to do your part to end this trust deficit.
Observe behaviour of individuals:
You may find yourself in a situation when there is nothing wrong in the organisation but you can feel some negative vibes at the individual level. Do not ignore if someone around you has suddenly become an introvert or started hiding things from you. It can be initial signs of mistrust so prompt action can be helpful in reviving the bond of trust.
Encourage free conversations:
Sometimes, all you need is a catharsis so encourage open communication. If you feel something wrong then do not just hide rather say it in a nice manner. Similarly, motivate others to talk freely and share their feelings. Do not hesitate in admitting your fault as this will bring the other person close to you.
Share your ideas:
If you are working in a business organisation then share your thoughts, ideas, plans or even fears with your colleagues. Keeping secrets gives the impression that you don’t trust them so ultimately they will also keep you at distance. Remember, it is a chain reaction. Do not try to give a statement that you are perfect and do not belong to them.
Keep your promises:
You can raise the level of trust by honouring all your commitments. If you are unable to keep your promise then apologise to the other party and give a valid reason.
Value the difference of opinion:
It is not necessary that others also think in the same direction as you do so respect their ideas. Give them the impression that you value that difference of opinion.
Appreciate others even for the minor achievements and console them in case of failures. Offer your assistance in difficult tasks.
