My opinion:

i) Don't expect your subordinate can perform job as you do..Some people need to adapt with the environment before they can start to perform

ii) Only foreign Uni graduate? Local grads can't do any job?? I saw a lot of "Foregn Uni" grads unable to perform compared with the local grad. Mostly come-out from their uni with an egoism as a package but unable to perform and always ask question without effort to find answers by themselves.

iii) 70 hours for 5 days a week (14 hours)..is that your minimum working hours? It is totally not worth even you pay them with 5k...as I mention, the new joiners need some time to adapt..but at the same time not to pampered them.

iv) If you do want people to work that hard...why don't you take 2 person and pay them rm2.5k? Atleast if they can work 9 hours (normal working hour) daily, with 2 of them, you can get around 90 hours per week consistently. At the same time don't be too strict on the requirement.

Thanks
