Landlord bypassing property manager?

[Eleanor Weiss]

Having survived into my 80s, and having been a member of many different organizations and party to a number of contracts, I know that "bypassing the chain of command" is a universal issue.  Happens a lot in the wider world.

I have a friend who is an independent property manager with maybe 10 - 20 clients at any one time.  She is a very conscientious person who puts considerable effort into upholding her responsibilities.

She repeatedly reports having landlords, (her clients,) bypass her position as property manager, going directly to tenants and/or contractors.

In addition to reducing her income, this is, naturally, difficult to work around, and is also going to happen again.

Being that this isn't uncommon, has anyone on this forum come across some contract clauses which anticipate this happening, and lay out procedures for handling this problem which are satisfactory to both property managers and landlords?

Thanks for advice on this.
