The administration of the blood bank is forcing clients to donate blood

I am a governmental clerk in a blood bank, and I have two questions: 
First question: 
The medical examination needed for issuing or renewing a driving license is performed in the blood bank. The commands of the health ministry to us include that: (A person who requests to issue or renew a driving license has the option to donate his blood if he is healthy. The medical examination is for free whether he accepted or refused to donate). But what actually happens is that the administration forces the clerks to donate, and if they refuse, then it directs them to a private hospital to have the examination done, which they will have to pay for. Then they should return to the blood bank to get the papers approved; (the only accepted stamp by the traffic administration is this blood bank stamp). So many clerks donate their blood forcibly to complete the procedures. What is the ruling on this regarding the individuals in charge, and the clerks? What do you advise us to do in case the administration insists on this? 
Second question:  
The instructions of health ministry includes that the day working hours are from 07.30 to 16.30, Saturday to Thursday. And the night working hours are from 15.30 to 23.30. But what actually happens is: the clerks working at the day leave when the clerks working at the night come, meaning 15.30 and sign for leaving, which should be done 16.30. The clerks working the night hours start their work 15.30, so there is no need for the day clerks to be there. What is the ruling on signing for leaving 15.30 considering it 16.30, knowing that this does not make any difference to the regularity and quality of work? .
