"Because of the thousands of job losses that have happened most of our members have taken on additional responsibilities - therefore we do not believe the hikes in executive salaries are justified," general secretary Gerry Morrissey told the BBC News website.
In October, the BBC announced it was axing up to 1,800 jobs, prompted by a smaller than expected licence fee settlement from the government.
"Nobody in the executive board leading the BBC should be taking higher salary increases than the across-the-board increases that have been given to staff, who are only getting 2% this August," Mr Morrissey added.
Paul McLaughlin, national broadcasting organiser of the National Union of Journalists, criticised a "two-tier policy on pay".
"I don't think the BBC needs to act competitively to attract talent - people want to work for the BBC whether it pays huge bonuses or not," he added.
Mark Thompson and Michael Lyons questioned about BBC executive pay
BBC Vision director Jana Bennett saw her total pay package increase by more than £103,000 to £536,000. But Mr Thompson said her bonus had been reduced to £23,000 because of fakery scandals surrounding some TV shows.

In July 2007, the BBC suspended all competitions after an inquiry unearthed a fresh batch of faked phone-ins on six shows including Comic Relief. That followed early problems with phone-ins on Saturday Kitchen and Blue Peter.
In the same month, a documentary trailer that used footage out of sequence to falsely portray the Queen walking out of a photo session "in a huff" was shown to journalists.
At the start of 2007, licence fee payers questioned in a survey gave a mean score of 5.87 out of 10 for how much they agreed with the statement "I trust the BBC", the report said.
This began to drop after July 2007 and had fallen to 5.49 by October but, by May 2008 had returned to 5.89.
