The facts
Both CFMEU and CEPU are organisations registered under the Workplace Relations Act . Curragh employs members of both unions at its mine. Some time ago, it seems, both unions made demands on Curragh that were not satisfied and gave rise to industrial disputes. The Commission numbered the dispute generated by CEPU's claim as C No 00154 of 1993 and two CFMEU disputes as C No 22841 of 1995 and C No 40167 of 1997.
On 11 March 1997 the District Secretary of CFMEU gave Curragh a notice of initiation of bargaining period under s 170MI of the Act. On the following day CEPU gave a similar notice. It is not necessary to set out the terms of either notice. Curragh concedes CEPU's notice was effective to initiate a bargaining period. Curragh disputes the efficacy of the CFMEU notice but only because it identifies the proposed nominal expiry date (a particular required by s 170MJ(e)) as "the date two (2) years from the date of the agreement's certification". Curragh says it is necessary to specify a calendar date.
It seems the unions offered Curragh a draft certified agreement and negotiations ensued. However, no agreement was reached and, on 16 April, both unions gave notices of proposed protected action. The CFMEU notice was signed by the General President of the Union and addressed to the Chief Executive Officer of Curragh. It read:
"You are hereby advised of the intention of members of the Construction, Forestry, Mining & Energy Union employed by Curragh Queensland Mining Ltd. at Curragh Mine to take industrial action for the purpose of supporting and advancing claims made by the Union that are the subject of the industrial dispute found in C No.22841 of 1995.
Such industrial action will take the form of overtime bans, bans on the use of contractors, work-to-rule, stop-work meetings and rolling stoppages and will commence at nightshift Sunday 20 April, 1997."
The CEPU notice consisted of a letter from the Assistant Divisional Secretary of the union to Curragh in these terms:
"Under s 170MO of the Workplace Relations Act 1996 the Communications, Electrical, Electronic, Energy, Information, Postal, Plumbing and Allied Services Union of Australia (CEPU) hereby gives formal notice of the intention of its members employed by Curragh Queensland Mining Limited to engage in industrial action.
The intended industrial action is for wage increases and other conditions of employment that the Union and its members seek to be included in a Certified Agreement pursuant to the provisions of Division 4 of Part VIB of the Workplace Relations Act 1996.
The industrial action will commence from 21st April, 1997.
The nature of the intended action is the engaging in, by officers, employees and members of the CEPU, of such action as described below:
(i) the performance of work in a manner different from that in which it is customarily performed, or the adoption of a practice in relation to work the result of which is a restriction or limitation on, or a delay in, the performance of work;
(ii) bans, limitations or restrictions on the performance of work, or on acceptance of or offering for work;
(iii) a failure or refusal by persons to attend for work or a failure or refusal to perform any work at all by persons who attend for work;
(iv) protests at or around the place where agreement is sought and/or other relevant places;
(v) some combination of the above, either at the same time or at different times."
CFMEU commenced industrial action on 20 April but the evidence does not establish its form. On 23 April Curragh's CEPU members staged a 24 hour strike.
On 6 May the General President of CFMEU issued a further notice to the Chief Executive Officer of Curragh. It followed the notice of 16 April except that it referred to dispute C No.40167 of 1997 and the commencement of industrial action as being "at afternoon shift - Friday May 9, 1997". On 8 May the Curragh Lodge President issued a further notice addressed to Curragh's Human Resources Advisor stating that CFMEU members employed by the company "will be commencing a two (2) week stoppage from 3pm, Friday May 9, 1997". He said this was to support the claims in C No.40167 of 1997.
On a date that does not appear, the CEPU President notified Curragh that the members of his union, also, would commence a two week stoppage from 3pm (the commencement of afternoon shift) on Friday, 9 May. He said this was for the purpose of supporting the claims in matter C No.20557 of 1997.
At the commencement of afternoon shift on 9 May, the members of both unions - and, I understand, AFMEU as well - commenced a strike that lasted until 25 August. However, neither union treated the strike as one of indefinite duration. Both unions gave a succession of notices under 170MO that referred to a "two week stoppage" commencing at afternoon shift on a particular day. The CFMEU notices were in identical terms and addressed by CFMEU's General President to the Chief Executive Officer of Curragh. I need quote only the first such notice, dated 20 May 1997:
"You are hereby advised of the intention of members of the Construction, Forestry, Mining & Energy Union employed by Curragh Queensland Mining Ltd. at Curragh Mine to take industrial action for the purpose of supporting and advancing claims made by the Union in respect of the matters annexed to the notice of initiation of bargaining period in C No.40167 of 1997 and the proposed agreement as served on the Company on May 9, 1997.
Such industrial action will take the form of a two (2) week stoppage and will commence at afternoon shift Friday May 23, 1997."
Subsequent notices were given on 3 June, referring to industrial action to commence at afternoon shift on Friday, 6 June; 17 June referring to 20 June; 1 July referring to 4 July; 15 July referring to 18 July; 29 July referring to 1 August; and 12 August referring to 15 August. There may have been later notices as well but there is no evidence of them. The CEPU notices were not in identical terms. They were given at fortnightly intervals and referred either to "industrial action for a further 2 weeks" or "a two (2) week stoppage" from 3pm on a particular Friday. Each referred to supporting the claims made in connection with dispute C No.20557 of 1997. Some of the notices were dated the same day as the stoppage was to commence, others earlier but never more than three days before the projected commencement date.
On 4 August 1997 the Managing Director of Curragh, Bruce Douglas Denney, wrote a letter to all employees concerning the negotiations that had ensued between the unions and the company. He said that "despite 12 weeks strike we are no closer to resolving the fundamental issues. All the Company is trying to do is to put in place an agreement which will both ensure long term viability of the mine and fair conditions for all employees". He asked the addressees to "take some time to think about where we are at on these key issues". Mr Denney then dealt with three matters: salary levels, the use of contractors and demarcation. He concluded:
"If we can finalise these key issues of $'s, contractors and demarcation then we are a long way down the road to solving the whole issue. What we are asking is for commonsense in return for good $'s.
I need to say that we are in this for the long haul. Life will not get back to normal for any of us until after these issues are resolved.
We will not do a deal that doesn't fully solve Curragh's problems. Despite extensive negotiations the union appears not to be capable of presenting a feasible solution to solve these problems. You do however have the solution in your own hands. I urge you to accept our very fair enterprise agreement offer and return to work."
The letter contained no reference to the agreements, at State or local level, which Curragh had made, over the years, with unions representing its employees and which conferred on them benefits beyond those provided by industrial awards.
Nonetheless, on 6 August, Mr Denney wrote letters to the secretaries of the local branches of both CFMEU and CEPU stating:
"You are advised that Curragh Queensland Mining Limited will withdraw from all State Level and Local Agreements, whether written or otherwise, signed or unsigned, or custom and practice, one month from the date of this letter."
On 14 August 1997 Mr Denney announced the recommencement of coal production "using all available labour". He said the striking employees would be offered three alternatives: voluntary redundancy, a return to work under an Australian Workplace Agreement ("AWA") or remaining on strike at the picket line. On the following day, letters were sent to the striking employees offering each of them an individual contract of employment in the form of an AWA.
As a result of these (and other) events, on 18 August 1997, the General President of CFMEU notified the Commission of an industrial dispute. At about the same time, the Commission also received a notification from the Australian Collieries' Staff Association complaining of Curragh's proposal that its members (who were not on strike) undertake work that normally would be performed by the striking employees. This complaint was investigated by Commissioner Bacon. On 19 August he issued a recommendation that Curragh use only volunteers from employees currently at work to perform the work that would normally have been undertaken by striking employees.
Commissioner Bacon conciliated the applicants' dispute with Curragh but without success. On 21 August he ordered the termination of the bargaining period, as from the following Monday, 25 August, and recommended a return to work on the basis of continuation of all pre-strike conditions. On the following day, the striking employees agreed to accept the recommendation. They returned to work on 25 August.
Thereafter, conciliation proceedings continued; the pre-strike conditions continuing to operate. A final draft enterprise agreement was sent to Curragh on 16 September. However, on 24 September 1997 Mr Denney advised Commissioner Bacon and the unions that the draft was not acceptable. On the following day Curragh issued a notice to the members of all three unions that included the following announcement:
"CQML advise all unions that effective from 3.00 pm Thursday 25 September 1997 the Company intends to operate under the terms and conditions of the 'The Coal Mining (Production & Engineering) Interim Consent Award, September 1990 (the Award).
All previous customs, practices, arrangements, understandings or agreements written and unwritten will cease to apply to the Company's operations.
Contractors will commence to operate in areas of the mine as previously advised by the Company."
The notice offered an interim agreement that included a production bonus calculated in accordance with a specified formula but capped at $180 per week. That offer was rejected at a mass meeting of employees on 25 September. However, one week later, a further meeting accepted an amended offer that removed the cap on the production bonus.
At the request of the unions, the Commission listed the matter for arbitration before a Full Bench. On 21 October the Full Bench set a timetable for the projected hearing. On the following day, the employees at the mine held a one-day stoppage; apparently because CFMEU members had observed staff employees carrying out work normally undertaken by them. As a result of the stoppage, Curragh withdrew from the interim agreement and reverted to the award conditions.
On 30 October 1997 CFMEU applied for an interim award covering various matters dealt with by the State and local agreements. On 1 December 1997 the Commission rejected this application. The arbitration proceeded in the early months of 1998. On 11 August 1998, shortly before the hearing of this proceeding, the Full Bench of the Commission handed down a decision in which it specified the terms of a new award. They included a new salary and classification structure without a discrete bonus. Because the Commission thought the financial penalty inflicted on CFMEU members by loss of the bonus in October 1997 was excessive, the Commission ordered reinstatement of the bonus from the first pay period in 1998 until the commencement of operation of the new salary and classification structure. The Commission declined to include in the new award provisions to the effect of the other conditions of the State and local agreements.
