Higher Education workers are due take strike action this morning in response to a pay offer of a 1%.
UNISON Cymru says it will be taking industrial action and holding a picket line at Cardiff University alongside Unite and University and College Union.
Simon Dunn, UNISON Cymru/Wales higher education lead, said, "Some of our members in higher education are not even paid a living wage and most have experienced a real term drop in wages of almost 15%. That is bound to have a devastating impact on people's lives.
"And to add further insult to injury, Chief Executives' and Vice Chancellors' pay is extremely generous, with the highest paid vice chancellor in Wales receiving £264,000 a year."
Staff at Crown Post Offices across Wales are to hold another strike next week over proposals to offer their sites for franchise. Workers at Neath, Carmarthen, Morriston, Port Talbot, Holyhead and Llangefni held pickets during the Easter weekend over fears that their services will be downgraded.
But the Post Office says that it faces harsh commercial realities.
The Communication Workers Union (CWU) claims that plans to close or franchise 70 of the UK’s biggest post offices - known as the Crown network - will affect hundreds of jobs.
Dave Ward, the CWU's deputy general secretary, said, "Our Post Office members are standing up against destructive plans which would slash 20% of the Crown network and are simply asking for fair treatment and job security.
"The Post Office's plans are short-sighted and would rob the network of the most productive offices while simultaneously putting hundreds of jobs at risk and potentially damaging local economies.
“We'd like to see a better vision for a successful network which maintains services in the heart of communities alongside quality jobs.
"We're confident this could be achieved if Post Office management would agree to negotiations".
Responding to George Osborne's announcement on regional pay for civil servants, the TUC President in Wales Andy Richards says strikes can't be ruled out. He said there was no justification for regional pay
