Trade Union Recognition Tanzania: What Employers Must Do in 2026

Trade union recognition Tanzania rules apply the moment a union starts recruiting your staff, not only when it asks to bargain. The Employment and Labour Relations Act, Cap. 366 R.E. 2023 (ELRA) gives a registered union rights in stages. A union with a few members can enter the premises and collect dues. A union with a majority can demand recognition as the exclusive bargaining agent. This guide sets out each stage, the deadlines, and what an employer may and may not do.

Section numbers below follow the R.E. 2023 text on TanzLII (version at 31 December 2023). That revision moved every section from section 12 onward up by one. Older CMA awards and many guides still cite R.E. 2019 numbers, so check which edition a document uses.

What the law says

Four instruments govern union relations on the Mainland. ELRA Parts IV to VII cover registration, organisational rights, collective bargaining and strikes. The Labour Institutions Act, Cap. 300 creates the Commission for Mediation and Arbitration (CMA) in section 12, the Essential Services Committee in section 29, and the Labour Commissioner and Registrar of Organisations in section 43. The Employment and Labour Relations (Code of Good Practice) Rules, GN 42 of 2007 are codes made under the Act. Section 100(3) of ELRA requires anyone who departs from a code to justify the departure. The Labour Laws (Amendments) Act, No. 4 of 2025 then amended parts of ELRA and the Labour Institutions Act.

Who is affected?

ELRA section 2 applies the Act to all employees in Mainland Tanzania, public service included. It excludes the armed forces, police, prisons, National Service, the Fire and Rescue Force and the Immigration Services Department. Every private employer on the Mainland is covered, whatever its size. Size matters only for some rights. A field branch needs ten members at the workplace, and the number of union representatives rises with membership.

Manufacturers, hotels, mines and logistics firms with large non-managerial workforces see the most union activity. HR and payroll teams also need these rules, because union dues carry a seven-day remittance rule and a daily late charge.

Can an employer stop staff from joining a trade union?

No. Section 9(1) gives every employee the right to form and join a trade union and to take part in its lawful activities. Section 9(3) and (4) bar discrimination against an employee for union membership or activity, and contravening them is an offence. Under section 103(3), offences under sections 7, 8 and 9 carry a fine not exceeding five million shillings. Section 38 makes a dismissal for union membership or for exercising a statutory right unfair.

There is one limit on who joins which union. Section 9(2) says senior management employees may not belong to a union that represents non-senior staff. Magistrates and prosecutors may join only unions restricted to their own groups. Employers have a matching right under section 10 to form and join an employers' association.

Questioning staff about membership, moving members to worse shifts or rewarding those who stay out can turn an ordinary disciplinary hearing into a discrimination claim. Since Act No. 4 of 2025, a termination found unfair for discrimination carries compensation of 12 to 24 months' remuneration.

How does a union become registered?

Under section 46, a trade union must register within six months of its establishment, and operating without registration is an offence under section 46(3). Section 47(1)(d) requires a union to be established at a meeting of at least 20 employees. It must also be bona fide, not for gain, independent of employers, and have a constitution, a lawful name and an address in Tanzania. Registration is with the Registrar of Organisations appointed under section 43(2) of the Labour Institutions Act.

Before granting any right, ask the union for a copy of its registration certificate. Most Part V and Part VI rights belong only to a registered union.

What rights does a union get before it has a majority?

Part V of ELRA gives organisational rights to a registered union, even one with a minority of staff. The union starts the process by notifying the employer in the prescribed form under section 65(1). Within 30 days the employer must meet the union to conclude a collective agreement granting the right and setting out how it is exercised. If there is no meeting or no agreement within 30 days, the union may refer the dispute to the CMA for mediation, and then to the Labour Court.

How must union dues be deducted and paid?

Section 62(1) requires the employer to deduct dues once an employee authorises it in the prescribed form. The employer must remit the money to the union within seven days after the end of the month of deduction. With each payment it must send a list of members and copies of any revocation notices. An employee may revoke the authorisation by one month's written notice to the employer and the union.

Late payment is costly. Section 62(3) makes an employer that remits late without reasonable grounds liable to pay the union 5% of the amount due for each day it stays unpaid. The dues rate itself is not set by the Act. Each union fixes it in its constitution, so ask for the constitution and deduct only the rate it states. Our payroll compliance guide covers the mechanics.

How many union representatives must the employer accept?

Section 63(1) scales representatives to membership. A union with 1 to 9 members gets one representative, 10 to 20 members gets three, 21 to 100 members gets ten, and more than 100 members gets fifteen. Above 100 members, at least five representatives must represent women members, if there are any. The union's constitution governs their election and removal.

How does trade union recognition work when the union has a majority?

Section 68 is the core rule. A registered union that represents the majority of employees in an appropriate bargaining unit is entitled to recognition as the exclusive bargaining agent. An employer may not grant exclusive recognition to a union that is unregistered or lacks a majority. The union notifies the employer in the prescribed form. The employer must then meet it within 30 days to conclude a recognition agreement, and the parties may extend that period by agreement.

If the parties cannot agree, the union may refer the dispute to the CMA for mediation. If mediation fails, either side may go to the Labour Court. The Court may order a ballot of the affected employees to test whether the union has a majority. In setting the bargaining unit it weighs factors such as bargaining history, shared interests and location, aiming for the least fragmentation.

Recognition brings three duties. Section 69 requires both sides to bargain in good faith. Section 71 requires the employer to disclose information relevant to bargaining. Privileged information, information the employer may not lawfully disclose, confidential information that could cause substantial harm, and private personal data without consent are exempt. Section 70 deals with loss of majority. If the union falls below a majority, the employer must give it three months to regain one. If it does not, the employer must withdraw exclusive recognition.

What is an agency shop agreement?

Section 73 lets a recognised union and the employer agree that non-members in the bargaining unit pay an agency fee. A closed shop that forces staff to join is not enforceable. The fee must not exceed the dues paid by members. All amounts go into a separate union account that may be used only for the socio-economic interests of employees at that workplace, never for political affiliation fees or candidates. The employer may deduct the fee without consent, subject to regulations.

What goes into a collective agreement and where is it lodged?

Under section 72, a collective agreement must be in writing and signed by the parties. It binds from the date of the last signature unless it says otherwise. It binds the parties and their members. Where the union is the exclusive bargaining agent, it also binds non-member employees in the unit. Unless the agreement provides otherwise, a party may end it on reasonable notice with reasons. The parties must lodge a copy with the Labour Commissioner. The registered copy is presumed authentic and may be enforced as a decree of court.

The Act sets no deadline for lodging, and no lodging fee appears in the Zatra fee register. Lodge the signed copy promptly and keep proof of filing. Disputes about the interpretation or application of an agreement go to the CMA for mediation and then to the Labour Court under section 75, unless the agreement sets its own procedure. Align the agreement with your employment contracts and workplace policies, because a recognised union will test both.

When is a strike or lockout lawful?

Employees may strike, and employers may lock out, only over a dispute of interest under section 76. A dispute of interest is any dispute that is not a complaint. A complaint is a dispute about applying or interpreting a contract, collective agreement or the law, and it goes to arbitration or the Labour Court instead. Section 77 bars strikes on matters covered by a binding collective agreement, arbitration award or first-year wage determination.

Section 81 sets five conditions for a lawful strike. The dispute must be a dispute of interest. It must be referred to the CMA in the prescribed form. It must stay unresolved at the end of the mediation period. A union must call the strike after a ballot under its constitution shows a majority of those voting in favour. The employer must receive 48 hours' notice after the mediation period ends. Section 87(4) sets that period at 30 days from referral, or longer if the parties agree in writing.

A lockout under section 83 follows the same steps, with 48 hours' notice to the employees or their union. During a lawful strike, section 77 bars the employer from using replacement labour. Section 84 protects strikers from dismissal and from civil or criminal action. The Labour Court has exclusive jurisdiction over unlawful strikes and lockouts under section 85.

Which services cannot strike?

Section 78 lists essential services. These are water and sanitation, electricity, health services and associated laboratory services, fire fighting, air traffic control and civil aviation telecommunications, and transport needed for those services. The Essential Services Committee, set up within the CMA, may designate others after a public hearing and Gazette notice. Disputes of interest in an essential service go to CMA mediation and then arbitration under section 79.

Outside essential services, the parties may agree minimum services under section 80. An employer may also apply for a minimum service designation to protect property, machinery or plant where no agreement exists.

What changed in 2025?

The Labour Laws (Amendments) Act, No. 4 of 2025 was published in Special Gazette No. 4, Vol. 106 of 14 March 2025. It amends ELRA using R.E. 2019 numbers. Clyde & Co (30 April 2025) reports four changes relevant here. Collective agreements in public institutions bind on approval of the Permanent Secretary. One or more trade unions may conclude a collective agreement. Parties must attend CMA mediation in person. A complaint must go to arbitration within 30 days after mediation fails.

Bowmans (28 March 2025) adds that a party who cannot attend may appoint a representative in writing. It also notes that employers may not start or continue disciplinary action once a matter is before the CMA or a court. The R.E. 2023 section numbers for the collective-agreement amendments should be confirmed against the amending Act. Section 68's majority rule for exclusive recognition was not reported as changed.

Should an employer join an employers' association?

Section 10 lets employers form and join employers' associations, which register under the same Part IV rules. Section 47 requires an employers' association to be founded at a meeting of at least four employers. Section 68 allows an employers' association to bargain and recognise unions on behalf of its members.

The Association of Tanzania Employers (ATE) describes itself as the most representative employers' organisation in Tanzania. It states that it is registered under ELRA and covers all sectors except the civil service. ATE offers labour advice, training and representation.

Mainland and Zanzibar compared

ELRA does not apply in Zanzibar. Zanzibar's Employment Act, No. 11 of 2005, section 12, says that freedom of association and collective bargaining are as provided in the Labour Relations Act, 2005. That Act is commonly cited as No. 1 of 2005, but we could not read its text for this guide. The Zanzibar figures below come from the ITUC Global Rights survey and must be confirmed against the Act.

Worked example: a 180-employee factory in Dar es Salaam

Kilima Plastics Ltd is a hypothetical manufacturer in Dar es Salaam with 180 employees. Twelve are senior managers. Under section 9(2) they cannot belong to a union that represents non-senior staff, so the likely bargaining unit is 180 − 12 = 168 employees. A registered union recruits 79 members and serves notice under section 65.

Stage 1: organisational rights. With 79 members the union has more than ten members, so it may form a field branch under section 61(2). Its membership is in the 21 to 100 band, so it may elect ten representatives under section 63(1). Kilima must meet the union within 30 days of the notice and agree access times, a meeting room and the dues process.

Stage 2: the majority test. A majority of 168 means more than half, which is 168 ÷ 2 = 84, so the union needs at least 85 members. At 79 it is 6 members short and cannot claim exclusive recognition yet. Three months later it has 97 members. That is 97 ÷ 168 = 57.7% of the unit, a majority. Kilima must now meet within 30 days to conclude a recognition agreement.

Stage 3: dues and the late charge. The dues rate comes from the union's constitution, not the Act, so this example uses a total, not a rate. Suppose dues deducted in October 2026 total TZS 1,200,000. They must reach the union by 7 November 2026. If Kilima pays on 11 November without reasonable grounds, the payment is 4 days late. The charge is 5% × TZS 1,200,000 = TZS 60,000 a day, so 4 × 60,000 = TZS 240,000 owed to the union on top of the dues.

Stage 4: agency fee. If Kilima and the union sign an agency shop agreement, the 168 − 97 = 71 non-members pay an agency fee no higher than members' dues. The money goes into the union's separate account. If membership later falls to 84 or below, Kilima must give the union three months to regain a majority before withdrawing recognition.

Union dues are not statutory contributions. They sit beside the employer's own payroll charges, which follow the official rates in the Zatra fee register.

What to do now

1. Check the union's status. Ask for the registration certificate, the constitution and the notice in the prescribed form. Confirm the union covers your sector.
2. Diary the 30 days. Record the date the notice arrived under section 65 or 68 and fix a meeting well inside 30 days.
3. Define the bargaining unit. List employees by grade and site. Separate senior management under section 9(2) and count the majority threshold.
4. Set up dues on payroll. Collect signed authorisations, deduct at the constitution rate, and remit with the member list by the 7th of the following month.
5. Agree access and facilities. Put meeting times, notice boards, rooms and representative time off into a short organisational rights agreement.
6. Brief managers. Tell supervisors not to question, threaten or reward staff over union membership. Route every union issue through HR.
7. Prepare for bargaining. Assemble the wage data you may have to disclose under section 71, and decide whether to bargain alone or through an employers' association.
8. Lodge the agreement. Sign the recognition or collective agreement, lodge a copy with the Labour Commissioner, and keep proof of filing.

How Zatra helps

Zatra's HR consulting team reviews union notices, maps the bargaining unit, drafts organisational rights and recognition agreements, and prepares managers for the first meeting. Our payroll compliance service sets up dues and agency fee deductions so that remittances reach the union on time. We also align handbooks and contracts so that union terms and company policy match. See our termination guide for the dismissal rules a union will watch.

Government fees are paid at the official rate and are separate from Zatra's professional fee. Zatra does not decide or guarantee any authority's outcome. Strikes, Labour Court applications, CMA arbitration, prosecutions, seizure of property and formal legal opinions go to an advocate of the High Court, whom we can brief and work alongside.
