Birmingham co-owner David Sullivan believes Carson Yeung is "damaging" the club by dragging out his takeover.
Bruce feels he is in limbo while the takeover drags on
And he insists the current board will not extend the buy-out deadline for the Hong Kong businessman beyond Christmas.
Yeung's takeover has put a freeze on any new contracts for Birmingham staff, including manager Steve Bruce.
Sullivan told the Daily Mail: "I cannot believe that Carson and his group do not realise how damaging their actions are for the club."
Yeung is expected to meet the Blues board and Bruce this weekend after flying back from Hong Kong to attend Saturday's home Premier League clash with Wigan.
And Sullivan added: "I'm shocked and disappointed that Yeung will not let the current board finalise a contract with our longest-serving and most successful manager."
But, after being frustrated by a lack of communication from Yeung's team, Sullivan has guaranteed that the situation will be resolved in the next eight weeks.
"They will not be given a single day's extension and things will not be allowed to drag on. Supporters have my guarantee that this will not continue after Christmas," he concluded.
