UCU said the failure of university employers to make an offer on pay and working conditions is undermining trust in negotiations.
The union was responding to UCEA's refusal to put any offer on the table at yesterday's negotiating meeting.
UCU general secretary Jo Grady said: 'UCU yesterday went into negotiations with university employers, represented by UCEA, to try to reach a deal on pay and conditions. Disappointingly, UCEA refused to make an offer for 2022/23 and again demanded that UCU suspend planned industrial action as a pre-condition to even receiving one. This is a deeply unserious way to negotiate.
'The trade unions present agreed to bring forward the 2023/24 pay round and we expect UCEA to make a serious offer before our next meeting on Monday 16 January.
