β Signing after the employee's start date
Why it matters: In common-law jurisdictions, an employee already working has given up nothing new β meaning restrictive covenants (non-compete, IP assignment) signed after day one may be unenforceable without separate consideration.
Fix: Always execute the contract before or on the first day of work. If circumstances require a later signature, provide a documented benefit β bonus, salary increase, or additional PTO β as fresh consideration.
