If I am 71 and still employed, am I required to take a minimum distribution from my current employer's retirement plan?

[Phillip1]

No.

Unless the plan is a SEP or Simple IRA, you can wait to take RMD’s until you retire. See the following from IRS Retirement Topics - Required Minimum Distributions (RMDs):

Beginning date for your first required minimum distribution

• IRAs (including SEP and SIMPLE IRAs)

• April 1 of the year following the calendar year in which you reach age 70½.

• 401(k), profit-sharing, 403(b), or other defined contribution plan

• Generally, April 1 following the later of the calendar year in which you:

• reach age 70½, or

• retire.

See the chart comparing IRA and defined contribution plan RMDs.
