Table 1
Construction of the locked-in status variable (the new values in brackets).
| Workplace non-preference | Perceived Employability | |
|---|---|---|
| Low | High | |
| 1 = Preferred job | NLI (1) | NLI (1) |
| 2 = Non-preferred workplace, but OK for now | RLI (2) | NLI (1) |
| 3 = Non-preferred workplace | LI (3) | NLI (1) |
[i] LI: being locked in, RLI: at risk of becoming locked in, NLI: not locked in.

Figure 1
The study hypotheses. For the cross-sectional hypotheses, both independent and dependent variables are measured at Time 1. For longitudinal hypotheses, the independent variables are measured at Time 1, whereas the dependent variable is measured at Time 2. Note that locked-in status baseline (Time 1) only is controlled for in the analyses of longitudinal relations (the dashed line).
