Once again we become arbiter in the *725 continuing tug-of-war between the municipalities asserting their rights under the "Home Rule Act"[1] and the rights of municipal employees who are denied the legal right to strike,[2] but who are also granted the right to collective bargaining representation.[3]
Because of the length of the names of the parties and the concerned agencies and a statute, namely the Detroit Police Officers Association, the City of Detroit, the Michigan Employment Relations Commission and the Public Employment Relations Act, we will use throughout the opinion the acronyms DPOA, MERC, PERA and refer to the City of Detroit simply as the "City".
With the adoption in 1965 of § 15 of the PERA,[4] municipalities became bound to bargain collectively with the representatives of their employees. Accordingly, the City recognized the DPOA as the bargaining representative of all patrolmen and policewomen of the Detroit Police Department on January 18, 1966. Negotiations for a collective bargaining agreement began in March, 1966 between the City and the DPOA and continued with interruptions through the spring of 1968. This case grows out of the complexities of those negotiations.
It would appear from the record that both parties approached the bargaining table with certain preconceived objectives. In addition to the traditional wage demands, the representatives for the DPOA sought to remove a 30-year-old residency requirement as a condition of employment. The DPOA also opposed the lowering of several recruitment qualifications initiated by the police commissioner *726 apart from negotiations.[5] The City, for its part, sought to initiate certain changes in the Policemen and Firemen Retirement Systems, (Detroit Charter, Title 9, Ch 7) recommended by the Mayor's Task Force Committee on City Finances. The proposed changes were to provide: (1) a retirement pay of 2% of average final compensation for each year of service without a ceiling of 50%; (2) a minimum retirement age of 55,[6] (3) an escalation clause of 2% per year, identical to that of general city employees; and (4) a guaranteed pension after 25 years of service. The pension changes were to be prospective in application with respect to future members while present members would have the option to come under the new program; an option exercisable within a limited deadline period.[7]
In the course of negotiations the City took certain actions to which the DPOA took exception. While the Detroit Labor Relations Bureau, with the support of the mayor, neared agreement with the DPOA in bargaining on the elimination of residency requirements, the Common Council, in separate action, conducted hearings and adopted a new ordinance which required all city employees to reside within the city limits, to which the DPOA expressed strong opposition. The association also opposed modification of police recruitment qualifications mentioned earlier.
Finally, the DPOA took issue with the Common Council's unilateral submission of the mayor's proposed amendments to the Policemen and Firemen *727 Retirement System charter provision to popular referendum[8] absent meaningful bargaining on pension matters. Moreover, the association objected to the City's insistence on discussing pension matters apart from other items subject to agreement such as promotion, seniority, and job classification.
On July 10, 1968 the DPOA filed a formal unfair labor practice complaint under MCLA 423.210(a) and (e); MSA 17.455(10)(a) and (e) with the State Labor Mediation Board.[9] The DPOA amended its complaint following passage of the retirement system referendum amendment charging the foregoing actions on the part of the City constituted a failure to bargain under PERA. Issue was joined on the following stipulated questions:
"1. Did the City of Detroit have the duty to bargain with the DPOA regarding residency requirements for policemen? If so, did the City of Detroit violate this duty to bargain by enactment of a residency ordinance?
"2. Did the City of Detroit have the duty to bargain with the DPOA regarding recruiting requirements for patrolmen? If so, did the City of Detroit violate this duty by making changes in the existing recruiting requirements?
"3. When an economic item which is the subject of bargaining, has been agreed to by the respective bargaining agents of the City of Detroit and the union, which has been approved by the mayor, does the Common Council's action in deleting said item from the budget constitute a refusal to bargain in good faith?
"4. Under all the facts and circumstances, did the City of Detroit have a duty to bargain at one time on all mandatory subjects of bargaining at the time of the conferences concerning the proposed retirement provisions changes?
"5. Did the City of Detroit bargain in good faith with *728 the DPOA on the subject matter of retirement provision changes?"
Successive hearings were conducted by the MERC trial examiner who decided that the DPOA charges were without merit. Exceptions were filed by the DPOA to the examiner's decision and upon review by the commission a decision and order issued March 18, 1971.
While MERC, in its opinion and order, passed upon all of the five issues set forth herein, only three of them were appealed to this Court  numbers 1, 4 and 5. We treat them seriatim.
As to issue 1, MERC ruled there had been no violation of the applicable section of PERA. Subsequent to the time this case was submitted to us, our Supreme Court spoke with finality thereto. See Detroit Police Officers Association v Detroit, 385 Mich 519 (1971). We read this opinion to mean that the City is entitled to impose such residency requirement. It did so. Hence, we hold that issue no longer mandatorily negotiable.
Issues 4 and 5 both relate to the pension and retirement system. On issue 4 MERC determined that pension and retirement terms are an essential part of an employee's terms and conditions of employment and thus a mandatory subject for collective bargaining. It further held that the City's insistence "on isolating one mandatory subject of collective bargaining from other unresolved issues constitutes a refusal to bargain under § 10(e) of PERA". This position has been taken by MERC in earlier employment decisions. We do not disagree therewith, except, of course, as to the constitutional guarantee of the contractual nature of pensions already vested and the absolute inviolability thereof. Const 1963, art 9, § 24. To this *729 extent then we affirm the holding of MERC as to issue 4.
Issue 5 as stated, in our view, does not delineate with precision the important legal question we are called upon to decide. In irreducible simplicity it is whether "Home Rule" city charter provisions which are in conflict with municipal obligations under PERA will prevail over the statute.
For the guidance of other municipalities and public collective bargaining units, we will try to strip that issue to its bare bones. What really happened in this case was that the mayor as the chief executive officer enlisted the aid of a "Task Force Committee on City Finances". He also had an executive staff member functioning as a bargaining representative. Under the charter, however, each or both for that matter, had limited powers because that document reposes final authority to approve "all contracts to which the city or any board or commission thereof" is a party in the Common Council. But even though the mayor, his committee and his executive assistant had advocated changes in the policemen's retirement system and the council by resolution had unanimously approved the recommended changes, there remained a barrier to effective municipal action. In 1941, the Policemen's and Firemen's Retirement System had been made part of the city charter, amendable solely by popular vote. MCLA 117.21; MSA 5.2100. Hence, the mayor, the council and all the king's horses and all the king's men could not change the involved charter provision without approval of the electorate. So the plan advocated by the City was referred by referendum to the electorate. It was approved.
But meanwhile back at the bargaining table, the DPOA was clamorously contending that the referendum *730 was of no legal force. Prospective changes in a pension and retirement system, said DPOA, are mandatory subjects of bargaining under PERA, and this requirement of the statute obtains over the charter provision.
We agree with DPOA. If the course followed by the City in this case were to receive judicial approval, the rights legislatively granted to public employees in return for divesting them of their legal right to strike would become meaningless.
It takes little insight to appreciate what a municipal employer and its electorate could do to the collective bargaining process if this procedure were allowed to stand. Any "Home Rule" city could merely write its pension and retirement system into its charter, and insulate any change therein from negotiations and settlement save with electoral approval. This to us is the exact converse of what the Legislature intended when it inserted bargaining rights for public employees into the statute.
We hold that the City did fail to bargain in good faith as to prospective changes in its retirement and pension system as here involved. We further hold to so do was an unfair labor practice remediable by an order of MERC. If necessary, we will issue an enforcement order compelling the City to bargain in good faith on this issue as required by MERC's decision. PERA prevails over the city charter for, among other reasons, the reason that it is a "general" law of the state. The Home Rule Act itself writes into its grant of powers the exception which pertains here. MCLA 117.36; MSA 5.2116.
"Sec. 36. No provision of any city charter shall conflict with or contravene the provisions of any general law of the state."
*731 To the extent then that the city charter conflicts with PERA, the charter must yield.
Affirmed as delineated herein. No costs  a public question.
All concurred.
