Having a laugh with co workers.
Sense of mutual purpose , and ability to help each other.
Stop making promises about future training and progression , and bonuses , that in reality , will never materialise
Stop treating employees as if they are "lucky to have a job" , and actually recognise who does the work and generates the turnover.
Dealing directly with issues , rather than simply relying on useless middle managers or appointing yet another "manager" to deal with things. Stop plugging the company as a "world class" employer , it isnt anywhere near.
Actually get paid for the job done , not just parts of it. Reward experience and length of service , not just bring in new people on more money as though they are doing you a favour.
