Johannesburg - Telkom acting CEO Jeffrey Hedberg's decision to not renew his contract at the end of March was a "calamity", trade union Solidarity said on Tuesday.
Spokesperson Marius Croucamp said Hedberg was an expert in turnaround strategies and his decision was a calamity for Telkom.
Last week Telkom announced Hedberg would not stay on after March.
Telkom could not afford to make more "political appointments", the union said.
"Telkom's dramatic decline of the past five years is undoubtedly attributable to the fact that three of the four Telkom chief executives during the period have been political appointments," said Croucamp.
"It is also widely speculated that government, Telkom's majority shareholder, would prefer a black CEO," he said.
"During his short tenure as CEO, Hedberg clearly stated his belief that a turnaround strategy for Telkom should be based on meaningful business considerations and not on politicking. That included, among others, the recruitment and retention of skills within Telkom, which could have lead to appointments at variance with Telkom's transformation policy," Croucamp said.
He said Telkom chairperson Jeff Molobela would probably not remain in office for much longer.
"Hedberg's resignation is a disaster. Telkom now needs the stability and leadership to successfully follow out a turnaround strategy," Croucamp said.
Hedberg was appointed Telkom's acting group CEO in July last year. He took over from Reuben September, who in terms of his contract was supposed to leave in November 2010, but left abruptly at the beginning of July 2010.
Hedberg was initially employed as CEO of Telkom's Nigerian subsidiary Multi-Links.
Boston-born Hedberg said within two weeks of his appointment as acting CEO that he saw "a great company" in Telkom.
Hedberg was credited with turning around mobile phone company Cell C during his tenure as CEO there from 2006 to 2009.
