Issue 2 - Alleged negligence of the employers
52It is beyond argument that as employers of the plaintiff, Mr Schofield and Mr Smith owed the plaintiff a non-delegable duty of care requiring them to take reasonable care for his safety in the workplace, including the duty to take reasonable care to maintain a safe system of work that avoids exposing him as an employee to unnecessary risks of injury: Modbury Triangle Shopping Centre Pty Ltd v Anzil [2000] HCA 61; 205 CLR 254, at [13] per Gleeson CJ; Bankstown Foundry Pty Ltd v Braistina [1986] HCA 20; (1986) 160 CLR 301, and other cases in that line of authority.
53In view of the findings on Issue 1, the determination of whether the plaintiff's employers were negligent must proceed according to the requirements of the substantive law of the ACT. This means that the alleged negligence of the plaintiff's employers stands to be assessed according to the common law of the ACT as modified by the Civil Law (Wrongs) Act 2002, and in particular, Pt 4.1 of that Act.
54The relevant sections of that Act are s 42 to s 45. Section 43 of that Act is in similar terms to s 5B of the Civil Liability Act 2002 (NSW).
55This requires a prospective analysis of whether the plaintiff's employers were negligent according to accepted common law principles: Vairy v Wyong Shire Council [2005] HCA 62; (2005) 223 CLR 442; Wyong Shire Council v Shirt [1980] HCA 12; (1980) 146 CLR 40.
56The relevant particulars of negligence relied upon by the plaintiff were as follows:
(a)Failure to heed repeated warnings by the plaintiff and other employees of the difficult nature of the lifting required.
(b)Failure to institute, devise and or maintain appropriate alternative systems for lifting including the use of more labour and/or mechanical assistance.
(c)Failure to stack the fencing posts by mechanical means closer to the site where they were to be inserted into the concrete.
(d)Required the plaintiff to lift and carry the fencing posts and bags of cement over a prolonged distance.
(e)Required the plaintiff to carry heavy loads over uneven surfaces thereby enhancing the risk of injury.
(f)Failure to provide suitable mechanical assistance in relation to the lifts including but not limited to wheeled trolleys, modified tractors, bobcats or forklifts or a purpose built designed small mobile crane.
(g)Failure to provide appropriate training in relation to safe lifting and manual handling techniques.
57Repetitive heavy labouring work of the kind the plaintiff was required to perform represented a foreseeable source of potential injury to him. I accept that this was well known to Mr Schofield and to Mr Smith. I accept the evidence of the plaintiff that the weights of the objects he was required to manhandle were very heavy and this represented a foreseeable source of injury to any workers who were required to perform those tasks: s 43(1)(a) of the Civil Law (Wrongs) Act 2002 (ACT).
58In the context of the work being carried out on a construction site on uneven ground and with the requirement that the plaintiff had to repeatedly lift, carry and manipulate heavy formwork segments and steel fencing posts, including with the need to perform some twisting movements under load, the risk of injury to the plaintiff was ever present and foreseeable, even where there was additional manual labour available to form part of the team allocated to carry out the work.
59The risk of injury to a worker in the course of handling heavy materials on a construction site is not an insignificant one: s 43(1)(b) of the Civil Law (Wrongs) Act 2002 (ACT).
60The risk that such work could cause injury to a worker engaged in the handling of the heavy materials on uneven ground as described by the plaintiff was an ever-present one, and therefore are that would ordinarily require a reasonable employer to take precautions against the risk of injury to workers: s 43(1)(c) of the Civil Law (Wrongs) Act 2002 (ACT).
61According to the unchallenged evidence of the plaintiff, before his injury when he pointed out to Mr Schofield the arduous and "ridiculous" nature of the work, he was met with the mocking response that he should "harden the eff up and stop wearing a skirt" as if the safety issue he had raised was just a joke: T41.6.
62Mr Schofield, who was present in court throughout the hearing, was not called to contradict that evidence given by the plaintiff.
63In my view, the response the plaintiff received when he raised that safety issue was not in accordance with a reasonable risk management response expected of a reasonable employer in the circumstances described by the plaintiff.
64I accept the evidence of the plaintiff that before he injured his back at the gaol site, he had repeatedly mentioned to Mr Smith the problems of carrying out the work on uneven ground, and that the workers on the job should not be engaged in lifting heavy formwork and the like: T39.25; T40.20 - T41.2. This was because the work could be performed more safely with mechanical assistance from machines on the site.
65I accept the opinion of Dr Adams that the manual handling tasks required of the plaintiff had the foreseeable potential to impose quite injurious stress upon the plaintiff's spine. This was from the perspective of both accumulative work stresses as well as an individual stressor that could cause a frank physical injury.
66I also accept the opinion of Dr Adams that prior to the plaintiff's injury it would have been well known to employers that there was a causal relationship between musculo-skeletal injury and the performance of tasks such as awkward or repetitive manual handling tasks, including lifting, carrying and manipulating heavy and bulky items. In my view, that description aptly applies to the tasks in which the plaintiff was engaged on the Canberra gaol site.
67I accept the opinion of Dr Adams that it was entirely foreseeable that the plaintiff, in being required to repeatedly perform such heavy work, could foreseeably suffer the musculo-skeletal injury to his lumbar spine, which in fact occurred due to the nature and conditions of his work: Dr Bodel. It is not necessary to determine whether the plaintiff's injury occurred as a result of the cumulative stresses to which he was subjected, or whether it was due to a single event. Both scenarios were equally foreseeable and could have applied equally: s 43(1) of the Civil Law (Wrongs) Act 2002 (ACT).
68I find that those physical work stresses to which the plaintiff was subjected in the work system employed could have been readily avoided by implementing reasonable, relatively simple and apparently inexpensive measures aimed at preventing the injury which the plaintiff has incurred: s 43(2) of the Civil Law (Wrongs) Act 2002 (ACT).
69Those measures included undertaking a comprehensive risk evaluation of the entire set of manual handling tasks inherent in the work system, proper training on site safety, and the provision of mechanical lifting and transportation aids to enable safe manoeuvring of the formwork components and the steel fence posts.
70In a system of work requiring the manual handling of heavy and awkward materials such as in the case under present consideration, the probability of injury occurring to a participant worker was high if reasonable precautions against injury were not taken: s 43(2) of the Civil Law (Wrongs) Act 2002 (ACT).
71The likelihood of serious harm occurring to an employee engaged in an unsafe system of work was a well known and obvious phenomenon that hardly needs stating: s 43(2) of the Civil Law (Wrongs) Act 2002 (ACT).
72The burden of taking precautions against the harm that occurred in this case was slight and inconsequential: s 43(2)(c) of the Civil Law (Wrongs) Act 2002 (ACT).
73There is no social utility in allowing unsafe work practices to prevail: s 43(2)(d) of the Civil Law (Wrongs) Act 2002 (ACT).
74Relatively simple and inexpensive safety measures were available to the plaintiff's employer.
75There was a bobcat machine on site. That could have been used in connection with lifting slings. If not, some similar small mobile lifting device could have been used in association with the machinery already on site. The evidence discloses that the plaintiff's employers did nothing to address the risk of injury associated with the requirement that the plaintiff participate in carrying and manipulating heavy loads over uneven surfaces.
76That risk could also have been readily and simply addressed by flattening the uneven ground of the work areas with machinery and by the use of mechanical lifting devices to eliminate the need for manual carrying.
77In particular, the task of lifting the fence posts in the vertical position and then manipulating them onto fixation bolt mounting points required the provision of reliable mechanical support to take the weight of the load, which was lacking in this instance. I accept the opinion of Dr Adams that this element of the work system was the most demanding of the plaintiff, and had the highest potential to cause injury.
78When the plaintiff pointed out problems with the work to his employer, instead of mocking him and challenging his manly capacity for manual work, the employers should have taken the opportunity of evaluating the scope for deficiencies in their system of work. The fact that they did not do so, and instead mocked the plaintiff in the manner already described, confirms to me the view that the employers had a cavalier and callous attitude to the safety of their employees, and that such an attitude was more probably than not present at the outset of the plaintiff's involvement in the job.
79Had the plaintiff's employers approached the question of safety with ordinary prudence, they would have ensured that the plaintiff was adequately trained and supervised for the performance of his work, including by induction into safe working practices, and to ensure that the tasks allotted to him were carried out safely. I find that all such measures were absent on this particular job and this is what caused the plaintiff to suffer his back injury as claimed.
80In my view, each of the particulars of negligence relied upon by the plaintiff, as outlined at paragraph [55] above, have been made out. I therefore find that Mr Schofield and Mr Smith were negligent in the manner alleged.
81Having regard to the unchallenged opinion of Dr Bodel, I am also satisfied that such negligence was the cause of the plaintiff's back injury which is the subject of this claim: s 45 of the Civil Law (Wrongs) Act 2002 (ACT).
