Financial services is where most Hong Kong restraint litigation happens, and where covenants have the best prospects. Firms here already run long notice periods, garden leave and detailed confidentiality regimes, which help a court see a coherent protective scheme rather than a reflexive ban. BFAM is the model: precise particulars of the trading strategies at stake, a six-month window, payment throughout. Licensing cuts the other way, and judges are reluctant to shut someone out of the only regulated activity they are authorised to perform.
Professional services and consultancy firms should lead with client connection rather than competition. The manager who has fronted an account for three years is the firm's relationship on paper and the client's in fact, and a non-dealing covenant tied to that account beats a bar on joining a rival.
Technology and data roles run into the shelf life problem head on. Manulife criticised the employer for failing to explain how long each category of information stayed confidential and why twelve months followed from it. Where the roadmap turns over quarterly, three months is often the honest answer, and a short restraint you can prove beats a long one you cannot.
Sales and commission-based roles produce the awkward cases. Courts accept that employees well down the hierarchy can hold real customer connection where the job is built on personal contact, but they draw a line at routine servicing work. Commission structures are useful evidence: an employee paid to grow an account rather than service it has the stronger argument made for them.
Junior and administrative roles should be left out altogether. Moxie is the cautionary tale: the employer there ended up with two unenforceable covenants and nothing to show for the litigation. A confidentiality clause and a clean return-of-property obligation protect the business better than a restraint that will not hold.
