For many years tax regulation and case law only recognised two categories of employment status, namely:

From a construction firm's operational perspective, it is understandable why they would wish to engage the same reliable and trusted individual contractors on a regular basis. The tax compliance conflict arises when the frequency of the engagements, or the nature of the working relationship, compromises the contractor's self-employed status. Treating the contractor as a 'worker' legitimises the arrangement.
Adopting a 'worker' status arrangement rarely proves popular in practice for either party. The engager has to process the contractor's remuneration through their PAYE scheme and suffer additional tax, and paid holiday costs. The contractor will find their right to offset self-employed expenses will be eroded when they come to prepare their self-employed annual accounts and tax return. They also often find the switch from receiving the majority of their income on a weekly to a monthly basis hard to manage.
Expediency and wishful thinking are rarely aligned with tax compliance. So, for the moment, using the 'worker' status working arrangement is the only tax-compliant option for engagers that wish to continue to use the same individual contractor on a regular basis and avoid the huge tax bill that will arise if the HMRC disagree with your tax treatment in a subsequent tax-investigation.
The current government has stated it plans to reform and clarify employment status as part of sweeping changes to employment law during their term in office. We shall see if the promised changes makes a very confused situation any better.
