How, depends on different factors. Without trust on the company, their manager and their peers and employee will be likely to quit.
Over the years, I observe trust being in direct correlation with 5 kpis:
* How often the word "politics" is being used in a daily base.
* Miss delivery (delivery something that don't fulfill the goal, in features or time).
* Miscommunication/misunderstanding. (The need of repeating the same message more than once).
* How often the word meeting is being used negatively.
* Times conflict was avoided.
Improving this kpis, by techniques mentioned in other comments, in my experience, will improve trust and employee retention.
