Instead, 2 years is a pretty common stretch before turnover in white collar jobs, especially for younger folk. Employees become better off from firm-hopping, and employers have no reason to offer long-ROI incentives such as paid masters' programs.
To make everyone better off, Hoffman suggests that we should introduce timeboxed contracts called "tours of duty" that explicitly state the true benefits for either party and the duration of the contract. I really am not a fan of misappropriation of military terms, but I guess it gets the point across.
For example, maybe a marketer wants to start a company, but an existing company needs a senior marketer to strategize and execute the plan for its next segment. The company could give the marketer opportunities to meet funding sources and receive education about company building, while the marketer can whole-heartedly deliver on agreed objectives for the time period of two years.
It's an idea that seems to straddle between W2 and 1099, as many of the "gig economy" jobs seem to do. Some further definition here may be welcome.
