It finds that strong unions that have a co-operative relationship with management prevent and heal breaches in the psychological contract and facilitate a virtuous trust cycle that is important to the implementation of NWP. This has significant implications for theory and practice, particularly in anti-union institutional contexts that are focused on union avoidance, suppression and substitution.

Standard first order P-values suffer from two important drawbacks. First, even for quite large sample sizes they can misrepresent the exact significance which depends on nuisance parameters unspecified under the null. For most discrete models is that accuracy is variable and breaks down completely at the boundary. Second, different test statistics can give practically different results.The bootstrap P-value is the exact significance with the null maximum estimate (ML) of the nuisance parameter substituted. We show that bootstrap P-values based on different first order statistics differ to second order. We also show that they are appropriately conservative on the boundary. We present numerical evidence that for discrete models mean inferential errors are of O(1/m) rather than O(1/m^(3/2)), as is the case for continuous models. However, worst case errors for bootstrap P-values are an order of magnitude smaller than for first order P-values, even for small sample sizes. The is partly due to boundary effects but may also be related to the way bootstrap corrects `incorrect' ordering of the sample space. This argument for this feature of bootstrap only holds when the null ML estimate is used.

More traditional human resource management is better suited to 'Low Road' business strategies that emphasise cost control and competition based primarily on price. Using data collected from a sample of 179 large Australian workplaces we tested the contingencies that influence HPWP implementation and impact. Our results support the Contingency approach in that High Road organisations are more likely to adopt HPWP and the Universal approach in that both High and Low Road organisations derive equal benefit from the implementation of HPWP. High Road organisations may be more likely to adopt HPWP because they see more benefit from their introduction or they may find it easier to implement HPWP because they have a less prohibitive union presence, a theory Y management attitude and a longer-term time horizon.
