Job lock

Job lock is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Job lock rather than just read about it. In short: The term job lock is used to describe the inability of an employee to freely leave a job because doing so will result in the loss of employee benefits (usually health or retirement related). In a broader sense, job lock may describe the situation where an employee is being paid higher than scale or has accumulated significant benefits, so that changing jobs is not a realistic option as it would result in significant…

Key takeaways

  • Job lock belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Job lock to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Job lock from memory before moving on to harder problems.

Reference excerpt

The term job lock is used to describe the inability of an employee to freely leave a job because doing so will result in the loss of employee benefits (usually health or retirement related). In a broader sense, job lock may describe the situation where an employee is being paid higher than scale or has accumulated significant benefits, so that changing jobs is not a realistic option as it would result in significantly lower pay, less vacation time, etc.

Overview Because the greatest source of insurance for most Americans is Employer Provided Health Insurance (EPHI) and an employee cannot take their EPHI with them when they leave their job, benefits-related job lock is a concern in the United States. The nonportability of EPHI is what causes workers to get locked into their present jobs, hence the term job lock. Bridget Madrian argued in 1994 that the link between EPHI and labor market mobility was an important factor in evaluating several proposals to reform the US health care system. The study by Madrian (1994) estimated that job-lock reduced the voluntary turnover rate of those with EPHI by 25 percent. Legislative efforts that have attempted to address health-insurance related job lock in the US are the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) and the Health Insurance Portability and Accountability Act of 1996 (HIPAA). However, employers can require their former workers to pay 102 percent of the full premium for COBRA among many other hurdles and HIPAA doesn't ensure that workers who change jobs will have access to health insurance coverage on the new job or that the coverage offered will be affordable. Thus, neither COBRA nor HIPAA ensures affordability of health insurance—the main cause of job lock.

Causes The potential for less extensive health coverage at the new job increases the financial risk associated with moving jobs, making change in jobs a very costly endeavor, so workers are more likely to stay locked into their current jobs instead of risking the job transfer. If employees knew that all their illnesses would receive identical coverage regardless of whether they worked, where they worked, or how long they had been on the job, health insurance would not be a deterrent to worker mobility. While health insurance may be purchased on an individual basis in states that permit medical underwriting, individuals with health conditions may be declined coverage as well as face high premiums or benefit exclusions. An example of a job lock due to a defined benefit pension plan would be someone who has been working for a company for 20 years, thus accruing a higher retirement income benefit. If they leave to work for another company their benefits are reset and they eventually realize a lower level of retirement benefits.

Prevalence A 1987 National Medical Expenditure Survey (NMES) that sampled married men in the United States aged 20–55 found job mobility rates were 30–31% lower among those with employment-provided health insurance coverage, compared with those without it. An NMES literature review in the same year found that studies typically reported a 20–40% reduction in mobility rates due to employment-related health insurance. A 1984 Panel Study of Income Dynamics examining mobility rates among full-time workers aged 25–55 found no statistically significant results. A Survey of Income and Program Participation (SIPP) (1985, 1986, 1987) found that state and federal policy to mandate continuation of coverage increased the job mobility of prime-age male workers. A 1984 SIPP found that for dual-earner married men and women, there was "strong evidence" of job lock among women, but "weak evidence" of job lock among men. When attempting to estimate how frequently job lock occurs, one must control for outside factors that may influence a worker's decision other than the risk of losing health care. Other factors can include initial wages and expected wage offers at new employment, other fringe benefits, experience, and job security.

Impact Job lock has three negative implications for society. One implication is that those who want to switch jobs prefer another job because there is a higher utility associated with it (e.g. better suits their skills and talents). However, if they are “stuck” at a job, the negative externality is that they are being inefficient workers and not as productive for the company and society. Workers are discouraged from switching to jobs where they are more efficient producers, and this immobility of labor resources leads to a lower level of overall productivity and national income. The second implication is that the high risk consumers are more likely to face job lock for fear of losing coverage for their routine medical expenditures (they know their expected value of health bills). Employers offer health insurance benefits to ensure that their workers are healthy and, therefore, productive workers. However, since job lock is common in the high risk employees, employers are ultimately keeping the high risk employees as a part of their company. The third implication has been coined by economists as "entrepreneurship lock". Similar to the issue of job lock, an “entrepreneurship lock” occurs when a person is hesitant to leave his or her job and become an entrepreneur, out of fear for losing health insurance and other benefits associated with the waged job. However, in this case they are not leaving for a separate job, but rather self-employment. Employer provided health insurance has been shown to significantly decrease the number of self-employed, and the bundling of health insurance coverage and employment together, has a negative impact on business creation in the US. Public health insurance (like in Europe) has been found to have a positive impact on the supply of businesses in an economy, because of the entrepreneur's positive contributions to the economy through job creation, innovation and economic growth. The entrepreneurship lock has a negative impact on both society and on the employee. In terms of society, decreased self-employment and entrepreneurship may have a negative impact on innovation. Furthermore, entrepreneurship has been shown to increase life satisfaction when compared to salary positions.

Worked examples

Example 1 — a first encounter with Job lock

Start with the simplest possible case. Write down what Job lock claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Job lock before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Job lock ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Job lock

In research
Job lock appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Job lock in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Job lock is common in secondary-school and first-year university syllabi. It links to neighbouring topics Demographic economic problems, Employee relations, Working time, so understanding it makes those chapters shorter.
In everyday life
Look for Job lock outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
