David Bowman, the head of environmental services, will have his pay increased from£70,600 to£76,000. Richard Evans, the director of social services, is to get a£6,300 pay rise to£85,000.
The city has hired consultants to review the salaries of other department heads, who earn between£70,000 and£85,000 a year. Another outside expert is to review the salary of Michael Lyons, the chief executive, currently earning£120,000 a year.
Unison regional officer Tony Rabaiotti criticised the pay rises. He said: 'I think the message this sends out is very wrong. Rises of eight per cent are unacceptable when the rest of the council workforce are looking at two per cent, or just over that. It tells staff in the social services department that while services are being cut the director is ensured a very high pay increase.'
She said: 'We are in a very competitive market and Birmingham has got to have a wide choice of the best skilled people.'
