I'm one of 3 employees that came to this company with the intention to professionalize it.
It is a family owned company, with a lot of management problems. My boss (52), founder of this 30 y/o hearing aids company, leader in the state, stays out quite a lot, he usually works only 1 or 2 week days at the office. He likes to enjoy his grandkids and wife and has some side non-related businesses as well.
He has a daughter (24) and a son (26), both work as audiologists, they are NOT prepared to keep the company moving forward. Other family members work here as well.
He knows his family is not capable of keep the company moving forward, so he hired 3 new professionals, which I'm part of. The company is structured as follows: 43 employees which 22 family members and 18 are non family members. All family members are either audiologists (which we consider our sales team) or financial/ administrative managers. Other 18 employees work as assistants or receptionists. Other 3 include marketing coordinator (me), expansion director and a senior audiologist.
We (3 new professionals) noticed that every time the boss is out, all of the family members work at 10% efficiency or do not work at all, side conversations, 1 hour coffee-breaks and so on. Every time he is at the office, they work at 120% effectiveness and are scared of committing mistakes or showing laziness.
We do not have cameras, we do not have well established KPIs, we do not have monitoring systems.
We want to tell our boss all these problems, but do not have such arguments besides our point of view. All changes (i.e. installing a vigilance camera system) has to go through his approval.
How can we manage to tell him that family members do not work productively when he is out?
