Parental grumbling about high school coaches is getting louder and more disruptive, fueled by growing use of Facebook and Twitter to spread displeasure with decisions as basic as about who plays and who starts.
Two longtime coaches who resigned last month both blamed, in part, parents using social media to amplify their vitriol. Coaches who counsel their players on the long-term damage caused by careless social media behavior are now increasingly reaching out for help to counter parents in need of similar restraint.
The shift comes as parents are becoming more forceful advocates for their kids, with coaches finding themselves targets of instantaneous and often emotional social media outbursts.
"In our estimation, it's created a hostile working environment," said John Erickson, executive director of the state coaches' association.
Tony Scheid, who coached the Stillwater High School girls' hockey team to two state championships in his 14 seasons, resigned on April 8 and lamented the rise of what he called "the public relations'' side of coaching.
"Decisions that are part of good coaching almost inevitably will lead to hard feelings,'' Scheid wrote in a letter to Superintendent Denise Pontrelli. ''Increasingly, this criticism has been voiced and amplified in mass e-mail communications and social media."
Ten days later, Brad Grimmius also cited parental pressures when he resigned after six years as head football coach at Worthington High School in southwestern Minnesota. Grimmius, a head coach for 14 years, said his wife read negative Facebook posts, which have since been deleted.
Carl Pierson, the Waconia High School girls' basketball coach, recalled the reaction after he made changes to his starting lineup three seasons ago. A Wildcats assistant coach told him, "Stay off Facebook because they are trashing you all over town."
