Allowing handyman to enter when a tenant is not there

[Matt C.]

Hello BP Forums, 

I've have lived in apartments where I usually let maintenance fix the issues when i am not there or at work.

Now, renting out properties my property manager and handyman do not like doing that and wants someone there, even though the tenants work doing the day.

I understand where the handyman is coming from, someone might blame him for stealing something. My question is are there things you guys do to allow a handyman to access a property without a tenant present? Is verbal approval of being unsupervised enough? Any help is greatly appreciated.
