It's time for @RepublicService to get back to the bargaining table in good faith and do right by the hardworking members of @Teamsters25. We will honor the picket lines for as long as it takes for these workers to see their work rewarded with dignity and a living wage.
Families and workers deserve to be treated equitably and with respect. We must have a system of accountability !
