By JOYCE M. ROSENBERGNEW YORK (AP) â¿¿ LaJuanna Russell has lost a third of her revenue and about half of her staff to federal budget cuts. "It has been just a very difficult year," says Russell, whose management consulting firm, Business Management Associates, has had contracts with federal agencies including the Pentagon and the Departments of Homeland Security and the Interior. The budget cuts, known as sequestration, slashed Russell's $3 million in revenue by $1 million. Her staff of 25 is now down to 13. Bob and Bonnie James saw every one of their company's existing federal contracts, including training work for the Army, Marines, Air Force and the government-funded Cherokee Nation Hospital, canceled when the cuts hit. The sequester erased tens of thousands in revenue and stamped out hiring plans. The $85 billion in budget cuts officially began March 1, but owners like Russell started feeling the impact last summer. Government employees cut contracts in advance, anticipating that they'd lose funding. Among those badly hurt were businesses that provide training and consulting services that aren't considered essential. Like Russell, they've had to lay off workers as their revenue plunged. There is some hope. Small business owners may get a boost from so-called 'use-it-or-lose-it' federal spending as the end of the government's fiscal year â¿¿ Sept. 30 â¿¿ approaches. Some report that they are hearing from agency contacts that they haven't spoken to in months. But end-of-the-year spending won't reverse the pain that contractors like Russell and Bob and Bonnie James have felt. The budget cuts have hurt them professionally and personally and have forced them to make tough decisions. A DEVASTATING BLOW Business Management Associates helps employers, including government agencies, come up with more efficient ways to get work done and assists with human resources issues. Under one contract, the company created a staff recruitment plan for the Department of Homeland Security. The Alexandria, Va., firm also provided support as the plan was carried out.
