Employment & Labour LawSenior Associate at Filion Wakely Thorup Angeletti LLP
Employment & Labour LawEmployers facing a union negotiation, a grievance, a human rights complaint or a wrongful dismissal claim can turn to Cassandra da Costa, a senior associate in the London office of Filion Wakely Thorup Angeletti. Cassandra's clients include public and private sector organizations of every size, and the aim is to bring a collaborative, creative approach to the knotty workplace problems they bring in.
Cassandra's U.S. work meant acting for a large American city on its labour and employment files: bargaining with its unions, working through workplace disputes and handling human rights matters. That all came before the Ontario call. Admission to the Washington bar came in 2014, Missouri followed in 2016 and Ontario in 2019. Ahead of joining Filion as an associate in January 2020, Cassandra worked at a London firm devoted to management-side labour and employment law.
That city work left Cassandra with a real feel for the politics, culture and socio-economic pressures local governments deal with. It's also why the workplace issues that come up with police services and utilities, and with the unions representing public sector staff, are familiar ground. And because Cassandra has practised in more than one jurisdiction, U.S. employers trying to find their way through Canada's workplace rules get someone who knows both sides of that line.
Cassandra writes and presents often for employers and HR teams, covering topics from federal termination requirements and pay equity deadlines to human rights damages and managing addiction issues at work.
Cassandra handles collective bargaining, labour disputes and grievance arbitrations for employers, and co-wrote a 2023 LexisNexis practice note on getting ready for interest arbitration.
On the litigation side, Cassandra defends employers against wrongful dismissal claims and deals with human rights and employment standards matters.
Cassandra drafts and advises on employment contracts and the policies that govern a workplace.
Cassandra understands how municipalities work, including the labour and employment issues facing police services and utilities and the unions that represent public sector staff.
