Relax. Change your attitude. Announce a new company policy.
Everyone is expected to be on time. If any one is late, they will be docked for the time they are late, plus a penalty of $10 from the annual bonus. Late time may be made up by staying late, but the penalty will still be taken. Unexcused days off will be penalized by a $20 fee. A doctor's note constitute a valid excuse. An additional $500 bonus reward for perfect attendance will be given at the annual picnic to those who qualify. (The carrot and the stick.)
This way, those who do show up are rewarded, and your star performer will not be released.
