Sparrow nurses and other health care workers picketed Tuesday night outside of the hospital in Lansing.
Their picket line was in an effort to raise awareness about their contract and staffing issues.
Nurses have been speaking out for months about safe "nurse to patient ratios" to prevent staff from being overworked.
Nurses say that Tuesday's picket was not a strike, any of the nurses that participated did so outside of their work hours.
FOX 47 News asked Sparrow to comment regarding the nurses complaints - a representative said that Sparrow has the best nurse-patient ratios in the state and that the 'state-wide union' effort is bringing up the patient ratios issue, but Sparrow's is good.
