Dozens marched in an informational rally to voice concerns and protest Mayor Tony Benavides' 2005-2006 budget proposal.
The majority of city of Lansing workers are represented by unions including U.A.W. local 2256.
Those workers say they've been without a contract since October of 2004.
Other workers say the mayor is asking for 2-point-5 million dollars in concessions to in part fill a 7-million-dollar budget hole.
Major union concerns include possible cuts in wages, healthcare and total staffing.
Additional concerns are fewer workers leading to fewer or reduced city services.
Despite the rally, the city says contract talks between local 2256 could continue Wednesday.
A representative for that local, however, says discussions are at an impasse.
