CENTRAL ARBITRATION COMMITTEE

TRADE UNION AND LABOUR RELATIONS (CONSOLIDATION) ACT 1992

SCHEDULE A1 - COLLECTIVE BARGAINING: RECOGNITION

DECISION ON WHETHER TO ACCEPT THE APPLICATION

The Parties:

National Union of Rail, Maritime and Transport Workers (RMT)

and

OCS Group UK Limited

1. Introduction

1)       National Union of Rail, Maritime and Transport Workers (RMT) (the Union) submitted an application to the CAC on 8 May 2026 that it should be recognised for collective bargaining by OCS Group UK Limited (the Employer) for a bargaining unit comprising “all non-management cleaning and maintenance employees working on the GTS Elizabeth line contract”. The location of the bargaining unit was given as “all locations.” The CAC gave both parties notice of receipt of the application on 8 May 2026. The Employer submitted a response to the CAC dated 11 May 2026 which was copied to the Union.

2)         In accordance with section 263 of the Trade Union and Labour Relations (Consolidation) Act 1992 (the Act), the CAC Chair established a Panel to deal with the case. The Panel consisted of Ms Laura Prince K.C., Panel Chair, and, as Members, Mr Rob Lummis and Mr Andy Peart. The Case Manager appointed to support the Panel was Joanne Curtis.

3)         The CAC Panel has extended the acceptance period in this case. The initial period expired on 22 May 2026. The acceptance period was extended to 9 June 2026 in order to allow time for the parties to comment on the results of a membership check and for the Panel to consider those comments before arriving at a decision.

2. Issues

4)         The Panel is required by paragraph 15 of Schedule A1 to the Act (the Schedule) to decide whether the Union’s application to the CAC is valid within the terms of paragraphs 5 to 9; is made in accordance with paragraphs 11 or 12; is admissible within the terms of paragraphs 33 to 42; and therefore, should be accepted.

3. The Union’s application

5)         In its application the Union said that it had sent its request for recognition to the Employer on 22 April 2026. The Union stated that the Employer had failed to respond to the request. A copy of the Union’s request letter was attached to the Union’s application. 

6)         When asked whether the Union had made a previous application under the Schedule for statutory recognition for workers in the proposed bargaining unit or a similar unit the Union answered, “no.” The Union stated that, following receipt of the request for recognition, the Employer had not proposed that Acas should be requested to assist the parties.

7)         The Union stated that the total number of workers employed by the Employer was 23880. The Union stated that there were 100 workers in the proposed bargaining unit, of whom 34 were members of the Union.

8)         In answer to the question whether the bargaining unit had been agreed with the Employer, the Union said “No”. The Union said that there was no existing recognition agreement of which it was aware which covered any workers in the bargaining unit.

9)         The Union confirmed that it held a current certificate of independence. Finally, the Union stated that it had copied its application and supporting documents to the Employer on 8 May 2026. The Union said it consented to its contact details being forwarded to Acas.

4. The Employer’s response to the Union’s application

10)       The Employer stated that it had received the Union’s written request for recognition on 22 April 2026. The Employer said that it had failed to respond to the request.

11)       The Employer confirmed that it had received a copy of the application form and supporting documents from the Union on 8 May 2026. The Employer stated that it had not, before receiving a copy of the application form from the Union, agreed the bargaining unit with the Union. The Employer stated that, following receipt of the Union’s request, it had not proposed that Acas should be requested to assist.

12)       The Employer said that the total number of workers it employed was “Circa 50,000. The Employer said that there were 93 workers in the bargaining unit as defined in the Union’s application. The Employer said that there was no existing agreement for recognition in force covering workers in the proposed bargaining unit.

13)       When asked whether it agreed with the Union’s estimate of membership in the bargaining unit the Employer answered “no”.   

14)       The Employer answered “no” when asked whether it was aware of any previous application under the Schedule by the Union in respect of this or a similar bargaining unit, and, “no” when asked whether it had received any other applications in respect of any workers in the proposed bargaining unit. The Employer said it consented to its contact details being forwarded to Acas.

5. The membership and support check

15)       To assist in the determination of one of the admissibility criteria specified in the Schedule, namely, whether members of the union constitute at least the required percentage (currently 10%) of the workers in the proposed bargaining unit (paragraph 36(1), the Panel proposed an independent check of the level of union membership within the proposed bargaining unit.  It was agreed with the parties that the Employer would supply to the Case Manager a list of the names, dates of birth and job titles of workers within the proposed bargaining unit, and that the Union would supply to the Case Manager a list of its paid up members within that unit (including their dates of birth).  It was explicitly agreed with both parties that, to preserve confidentiality, the respective lists would not be copied to the other party and that agreement was confirmed in a letter dated 14 May 2026 from the Case Manager to both parties. 

16)       The information requested from the Union was received by the CAC on 20 May 2026 and from the Employer on 26 May 2026. The Panel is satisfied that this check was conducted properly and impartially and in accordance with the agreement reached with the parties.   

17)       The list supplied by the Employer indicated that there were 93 workers in the Union’s proposed bargaining unit. The list of members supplied by the Union contained 32 names. According to the Case Manager’s report, the number of Union members in the proposed bargaining unit was 31, a membership level of 33.33%. 

18)       A report of the result of the membership check was circulated to the Panel and the parties on 26 May 2026, and the parties were invited to comment on the results of that check by noon on 2 June 2026.

6. Summary of the parties’ comments following the membership and support check

19)       In an e-mail to the CAC dated 27 May 2026 the Union stated that it did not wish to comment.

20)       In an e-mail to the CAC dated 2 June 2026 the Employer said “we are not disputing the findings, it is clear that the union have more than 10% membership in the proposed bargaining unit.”

7. Considerations

21)       In determining whether to accept the application the Panel must decide whether the admissibility and validity provisions referred to in paragraph 4 of this decision are satisfied. The Panel has considered all the evidence submitted by the parties in reaching its decision. 

22)       The Panel is satisfied that the application is not rendered inadmissible by any of the provisions in paragraphs 33 to 35 and paragraphs 37 to 42 and that it was made in accordance with paragraph 11 of the Schedule. The remaining issue for the Panel to address is whether the admissibility criteria set out in paragraph 36(1) of the Schedule are met.

Paragraph 36(1)

23)       Under paragraph 36(1) of the Schedule an application is not admissible unless the Panel decides that members of the union constitute at least the required percentage of the workers in the proposed bargaining unit. Paragraph 171B states that “the required percentage” currently means 10%. 

24)       The membership check conducted by the Case Manager (described in paragraphs 15-18 above) showed that 33.33% of the workers in the proposed bargaining unit (31 out of 93 workers) were members of the Union. As stated in paragraph 16 above, the Panel is satisfied that this check was conducted properly and impartially and in accordance with the agreement reached with the parties. The Panel has therefore decided that members of the union constitute at least the required percentage of the workers in the proposed bargaining unit as required by paragraph 36(1) of the Schedule.

8. Decision

25)       For the reasons given above, the Panel’s decision is that the application is accepted by the CAC.
