Feedback and constructive criticism
As the Brian Tracy blog states, one of the key ways to show you care about someone is providing them with quality feedback. That also includes constructive criticism, which helps the given person develop further. By actively listening to their subordinates and taking the time to formulate feedback, the manager shows they value their employees and want them to improve.
Involving subordinates in decision making
Avoid making decisions without the participation of subordinates. When making a decision within your team, listen to the opinions of regular team members. And when some decisions, such as company-wide ones, are made at higher levels and you have no say in them, at least explain them in detail to your team.
Development of individual employees' unique talents
Each employee has a unique skill or know-how that makes them special, something the whole team may benefit from. Support the specific strengths of the individual employees, make sure they develop them further, and enable employees to use them in their everyday work.
Taking a genuine interest in employees' wellbeing
Last but not least, it is necessary the manager takes a genuine interest in the wellbeing of their subordinates. This also applies to things not work-related. If you see a subordinate may have some personal issues, talk to them and ask whether they need some time off to recover.
