Depends on what you mean by "manage". The money is explicitly yours, the company can never touch it. However; you are locked into the company agreement with the custodian (e.g. Vanguard and their list of investment funds).
Not locked. You can roll it over into a IRA/ roth IRA and manage yourself. You won't pay early withdrawal taxes as long as you roll over within 60 days.

Rollovers typically only happen after employment has ended.
