Questioning the status quo comes with judgement from leadership. Those who get promoted are those who do not rock the boat and perform their job adequately.
High turnover is a result of the high stress, low reward environment. Many people leave the company without tying up loose ends on their accounts as a result of the low task identity. This creates a vicious cycle of coming into unhappy accounts that NEED Sovos because they have ingrained their tax compliance solution into their annual reporting process. Some introductions to clients contained airing a grievance about their previous service being inadequate.
As a result of the high turnover, it is evident that Sovos needs you more than you need them. Getting competent people to learn and use their software is their greatest service resource. Fortunately there will always be overqualified people leaving undergrad needing work.
This is many manager's first leadership experience, and the growing pains are not acknowledged or developed. Again- maintain the status quo, bring the clients through tax season.
