Many elements are necessary to keep your company culture healthy.
1- Passion for work in each employee.
2- Patience for listening to others.
3- No politics – discouraging back biters continuously really helps.And ignoring and abusing people publicly can create many troubles in one go.
4- Eating together. This works magically. How? No idea! But YES it works.
5- Uniforms – Yes this helps big way. People focus more on work instead of being superior or inferior in comparison to others. General clothes are cause of distraction and useless competition.
6- Small unexpected allowances or food packs or snacks or cakes.
7- Celebrations for small successes. People love partying. Keep it simple but keep doing it on regular basis. Send them back to home in happy moods.
8- Freebies once or twice a month. Everybody loves them by heart.
9- Be like a family. Keep them united and involve everybody in each big up and down. If it is a loss, gather them and discuss it. If it is a big success, share with them as well. Tell them that this is because of them.
10- Regular increments. They feel secure, stable and appreciated.
All the best .
