DES MOINES, Iowa (AP) — Iowa union leaders approached this legislative session with apprehension but say they never envisioned lawmakers would approve such dramatic changes governing worker rights and pay. GOP legislators, with support from Republican Gov. Terry Branstad, tightened the workers’ compensation system, limited the scope of collective bargaining rights for public employee unions and banned local minimum wage increases. Republicans say the changes will spur business activity.

BISMARCK, N.D. (AP) — Prolonged protests in North Dakota have failed to stop the flow of oil through the Dakota Access pipeline, but they’ve provided inspiration for protests against pipelines around the country. Tactics used in North Dakota such as resistance camps, social media and online fundraising are now being used against pipeline projects in nearly a dozen states. Some people don’t think their efforts will pan out under the Trump administration, which strongly backs the fossil fuel industry.

WATERLOO, Iowa (AP) — Authorities say an Iowa man’s drowning in the Mississippi River might have been avoided if the 52-year-old had been wearing a life jacket. The Waterloo-Cedar Falls Courier reports James Kenneth Freeman of Lansing, Iowa, drowned Friday after his fishing boat capsized and went under the dam gates near Genoa, Wisconsin.

DES MOINES, Iowa (AP) — Police are investigating a shooting that injured five people in Des Moines early Sunday. Investigators found more than 40 shell casings and evidence of drug activity at the scene of the shooting near J&J Pizza.

SIOUX CITY, Iowa (AP) — Parents and Sioux City residents are lamenting the latest delay in the opening of a new elementary school after several homes were demolished to make room for it. The Sioux City Journal reports that plans to start classes at the new Bryant Elementary School in the fall of 2019 unraveled March 14 after the low bid for the project’s final phase came in nearly $3 million higher than estimated. The main reason for the high bids is likely rising concrete costs.

The school board decided to revisit the architectural plans to save costs rather than pay more money, which superintendent Paul Gausman says will push the school opening to August 2020. Resident Erik Peterson says the dirt blowing from the construction site has created an annoyance for neighbors.

DES MOINES, Iowa (AP) — Iowa union leaders approached this legislative session with apprehension but say they never envisioned lawmakers would approve such dramatic changes governing worker rights and pay.

GOP legislators, with support from Republican Gov. Terry Branstad, tightened the workers’ compensation system, severely limited the scope of collective bargaining rights for public employee unions and banned local minimum wage increases. They also cut budgets amid a tax revenue shortfall.

Republicans say the changes ensure stability and will spur business activity. Others describe it as a war on workers. The director of labor education research at Cornell University, Kate Bronfenbrenner, says the changes may push more workers onto Social Security disability and Medicaid.

Union leaders worry the multiple changes regarding worker rights will spark unintended consequences, calling this session a nightmare scenario for workers.
