Restrictive covenants like non-compete agreements are increasingly being used in industries like hi-tech and finance during economic downturns to protect employers from losing competitive advantages and trade secrets. However, courts consider factors like the information's value, creation efforts, and whether the restrictions are reasonable in terms of duration, geography, and prohibiting future employment or business opportunities. While some states like California do not enforce non-competes, others may if the restrictions are deemed reasonably necessary to protect legitimate business interests rather than punish employees. Overall, restrictive covenants work best when narrowly tailored to specific trade secrets rather than broadly prohibiting competition.
