Slice chicken breasts into six pieces and season with salt and pepper. In a bowl, whisk together maple syrup and Dijon mustard until smooth. Coat chicken with half of the glaze.
Cook beef bacon in a skillet over medium heat until crispy; drain on paper towels.
In the same skillet, heat olive oil over medium-high heat. Cook chicken for 3-4 minutes per side until reaching an internal temperature of 165°F; brush remaining glaze during the last minute of cooking.
Assemble sliders by placing cooked chicken on buns, topping with beef bacon and arugula, then closing with the top bun. Serve immediately.
