A Universities UK (UUK) spokesperson said: "UUK are disappointed that UCU are preparing for additional industrial action that could further disrupt students' education."
"Both sides are currently engaged in serious and constructive talks at ACAS. We are committed to seeking a viable, affordable and mutually acceptable solution to the current challenges facing USS pensions."
"UUK has again restated its request to the union that industrial action is suspended while talks at ACAS continue. As part of any alternative proposal, we will expect that industrial action is suspended while UUK consults with all employers."
Talks started on Monday 5 March at ACAS between employers, represented by Universities UK (UUK), and employees by the University and College Union (UCU).
