Should a boss agree to give permission to an employee who is cheating on the company’s time?
Question

                Some employees leave work to deal with some other personal interests that have nothing to do with the job. They ask their boss for permission to leave, and they make up excuses which may or may not be convincing. If the boss knows that these excuses are not true, is he sinning if he agrees to give the employee permission to leave?
Praise be to Allah.It is not permissible for the boss or manager 
          of the department, or whoever is acting in their stead, to agree to 
          anything that he thinks is not right. He has to check on the matter. 
          If there is any need for this request due to an urgent need and if giving 
          permission will not affect the work, then it is OK. But if he knows 
          that an excuse is false or he thinks it is most likely to be false, 
          then he should not give permission and should not agree to it, because 
          that is a betrayal of trust and a lack of sincerity towards the one 
          who put him in this position of trust and towards the Muslims. Allaah 
          says (interpretation of the meaning): 
“Verily, Allaah commands that you should render back the trusts 
          to those, to whom they are due” [al-Nisaa’ 4:85] 
 And Allaah says, describing the believers: 
          
“Those who are faithfully true to their Amanaat (all the duties 
          which Allaah has ordained, honesty, moral responsibility and trusts) 
          and to their covenants” [al-Mu’minoon 23:8] 
 And He says (interpretation of the meaning): 
          
“O you who believe! Betray not Allaah and His Messenger, nor betray 
          knowingly your Amaanaat (things entrusted to you, and all the duties 
          which Allaah has ordained for you)” [al-Anfaal 8:27]
