Workforce productivity
The terms of art here for laziness like concepts are "shirking" and "effort", particularly  "endogenous effort" or "variable effort". You should also look into "efficiency wages". "Free riding" sometimes appears in this literature but because it is used heavily in the public goods literature it will have more false positives. 

This paper may also be of interest:


  Using a sample of male and female workers from the 1992 Employment in
  Britain survey we estimate a model of employees’ self-reported effort
  levels. Effort is modelled as a function of wages, the perceived
  monitoring and supervision environment in the individual's workplace,
  labour-leisure preferences, local unemployment rates and unionisation.
  Using a two-step estimation strategy to account for the endogeneity of
  the wage, we find that effort levels are increasing in wages and in
  preferences for work over leisure. While the extent of monitoring
  seems not to affect workers’ effort levels the ease with which they
  can be dismissed is a motivating factor. Unionisation reduces
  self-reported effort levels which may reflect the outcome of an
  effort-bargain and, in contrast to the efficiency wage shirking story,
  local unemployment rates do not affect effort. Finally, in spite of
  being paid more than women, men report exerting less effort at work.
