Practical career advice cautioning employees to secure a signed employment contract with a new employer before resigning from their current position. The article warns against premature resignation announcements (typically requiring 30 days' notice), which can backfire if the new employer cancels the hiring. Key recommendations: (1) thoroughly review and sign employment contracts before resigning, watching for exploitative clauses like unjustified security deposits or conditional final payments; (2) obtain a copy of the signed contract as legal protection. A new employer's refusal to provide a contract copy or behave professionally should be a red flag.
