National President of the three unions, Sam Ugwoke, announced the suspension at a media briefing on Thursday in Abuja, the Federal Capital Territory.
JAC comprises members of the Senior Staff Association of Nigerian Universities (SSANU), the Non-Academic Staff Union of Universities (NASU), and the National Association of Academic Technologists (NAAT).
The unions began an indefinite strike on September 11, following the government's failure to meet their 12-point demands, which include non-payment of earned academic allowances, shortfall in salaries of members, poor funding of universities, non-registration of Nigerian Universities Pensions Management Company and others.
"We have developed an actionable template with specific time frames to implement salient aspects of the agreement".
"In the event that no appreciable response is received from the government within 15 days of commencement of the strike by the Federal Tertiary Health Institutions, all our members in the states, and local governments nationwide are directed to join the action by September 28", Josiah said.
"Based on the foregoing and following exhaustive and extensive consultations with our various union organs, we hereby announce the suspension of the strike embarked upon by the Joint Action Committee of NAAT, NASU and SSANU, on the understanding that the time lines agreed with the Federal Government on the various issues are met", the statement said.
"We shall be reviewing the level of compliance with the agreement and shall not hesitate to resume the strike action if government reneges on the agreements reached or delays in any aspects", he said.
