How do you manage your subordinates when it comes to time management; in terms of work delivery and solving conflicts?

Imortant work to some experience colleaques who work is error less and always invites team management but knowing all the skills if adjustment is required.

in our case(that is our company) we provide staff transport,we also have cloaking system in place, and flexible working hours(shift planning)but the best of all is we set principles that all abide with.e.g the HR manual clearly states the reporting time. problem solving is usually handled at sectional level(supervisors) but it escalates to HR in case of deadlock.
