UCU said Universities Superannuation Scheme chief executive Bill Galvin was being rewarded for 'failure' after he received a salary of over £480k and bonus of over £100k.
The union was responding to USS's latest accounts.
UCU general secretary Jo Grady said: 'Whilst staff try to figure out how to manage the impact of USS pension cuts worth hundreds of thousands of pounds, Bill Galvin is wondering how best to spend his £100k bonus and his £480k salary. It is a disgraceful show of excess that will rightly be condemned by university staff up and down the UK.
