What internal roadblock occurs when an employee's responsibilities grow significantly but their title remains stagnant?

Answer

Future promotions or external moves may be benchmarked against the outdated, current title rather than actual work performed.

When titles don't match increasing responsibilities, future career benchmarks (for internal promotion or external moves) are often based on the lower, official title rather than the higher level of work the employee has been executing.
