The Intern (2015)

As her business begins to thrive, the founder of an e-business is told that her company is importing seniors to be interns as a community outreach effort, and she’s getting one. While her first question is whether they are seniors in high school or college, she learns to her horror that she’s getting a real senior, as in senior citizen. The over-70 widower is bored with retirement from a middle management career and initially seems like a fossil to his working mother boss, but grows more indispensable.
